CSS

Global CSS settings, fundamental HTML elements styled and enhanced with extensible classes, and an advanced grid system.

Working on an old existing project? You are probably after WVA Styleguide v1.1 docs.

The WVA styleguide uses Bootstrap 3's responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.

Introduction

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:

Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
Use rows to create horizontal groups of columns.
Content should be placed within columns, and only columns may be immediate children of rows.
Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.

Media queries

We use the following media queries to create the key breakpoints in our grid system.

/* Extra small devices (phones, up to 480px) */
/* No media query since this is the default in Bootstrap */

/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm) { ... }

/* Medium devices (desktops, 992px and up) */
@media (min-width: @screen-md) { ... }

/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-lg) { ... }

We occasionally expand on these media queries to include a max-width to limit CSS to a narrower set of devices.

@media (max-width: @screen-phone-max) { ... }
@media (min-width: @screen-sm) and (max-width: @screen-sm-max) { ... }
@media (min-width: @screen-md) and (max-width: @screen-md-max) { ... }
@media (min-width: @screen-lg) { ... }

Grid options

See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

	Extra small devices Phones (<768px)	Small devices Tablets (≥768px)	Medium devices Desktops (≥992px)	Large devices Desktops (≥1200px)
Grid behavior	Horizontal at all times	Collapsed to start, horizontal above breakpoints
Max container width	None (auto)	750px	970px	1170px
Class prefix	`.col-xs-`	`.col-sm-`	`.col-md-`	`.col-lg-`
# of columns	12
Max column width	Auto	60px	78px	95px
Gutter width	30px (15px on each side of a column)
Nestable	Yes
Offsets	N/A	Yes
Column ordering	N/A	Yes

Example: Stacked-to-horizontal

Using a single set of .col-md-* grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices.

.col-md-1

.col-md-8

.col-md-4

.col-md-6

<div class="row">
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
  <div class="col-md-1">.col-md-1</div>
</div>
<div class="row">
  <div class="col-md-8">.col-md-8</div>
  <div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
  <div class="col-md-4">.col-md-4</div>
  <div class="col-md-4">.col-md-4</div>
  <div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
  <div class="col-md-6">.col-md-6</div>
  <div class="col-md-6">.col-md-6</div>
</div>

Example: Mobile and desktop

Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works.

.col-xs-12 col-md-8

.col-xs-6 .col-md-4

.col-xs-6

<!-- Stack the columns on mobile by making one full-width and the other half-width -->
<div class="row">
  <div class="col-xs-12 col-md-8">.col-xs-12 col-md-8</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>

<!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
<div class="row">
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>

<!-- Columns are always 50% wide, on mobile and desktop -->
<div class="row">
  <div class="col-xs-6">.col-xs-6</div>
  <div class="col-xs-6">.col-xs-6</div>
</div>

Example: Mobile, tablet, desktops

Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes.

.col-xs-12 .col-sm-6 .col-md-8

.col-xs-6 .col-sm-6 .col-md-4

.col-xs-6 .col-sm-4 .col-md-4

<div class="row">
  <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
  <div class="col-xs-6 col-sm-6 col-md-4">.col-xs-6 .col-sm-6 .col-md-4</div>
</div>
<div class="row">
  <div class="col-xs-6 col-sm-4 col-md-4">.col-xs-6 .col-sm-4 .col-md-4</div>
  <div class="col-xs-6 col-sm-4 col-md-4">.col-xs-6 .col-sm-4 .col-md-4</div>
  <!-- Optional: clear the XS cols if their content doesn't match in height -->
  <div class="clearfix visible-xs"></div>
  <div class="col-xs-6 col-sm-4 col-md-4">.col-xs-6 .col-sm-4 .col-md-4</div>
</div>

Responsive column resets

With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes.

<div class="row">
  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>

  <!-- Add the extra clearfix for only the required viewport -->
  <div class="clearfix visible-xs"></div>

  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
</div>

In addition to column clearing at responsive breakpoints, you may need to reset offsets, pushes, or pulls. Those resets are available for medium and large grid tiers only, since they start only at the (second) small grid tier.

<div class="row">
  <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
  <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

<div class="row">
  <div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
  <div class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0">.col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0</div>
</div>

Offsetting columns

Move columns to the right using .col-md-offset-* classes. These classes increase the left margin of a column by * columns. For example, .col-md-offset-4 moves .col-md-4 over four columns.

.col-md-4

.col-md-4 .col-md-offset-4

.col-md-3 .col-md-offset-3

.col-md-6 .col-md-offset-3

<div class="row">
  <div class="col-md-4">.col-md-4</div>
  <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
</div>
<div class="row">
  <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
  <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
</div>
<div class="row">
  <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
</div>

Nesting columns

To nest your content with the default grid, add a new .row and set of .col-md-* columns within an existing .col-md-* column. Nested rows should include a set of columns that add up to 12.

Level 1: .col-md-9

Level 2: .col-md-6

<div class="row">
  <div class="col-md-9">
    Level 1: .col-md-9
    <div class="row">
      <div class="col-md-6">
        Level 2: .col-md-6
      </div>
      <div class="col-md-6">
        Level 2: .col-md-6
      </div>
    </div>
  </div>
</div>

Column ordering

Easily change the order of our built-in grid columns with .col-md-push-* and .col-md-pull-* modifier classes.

.col-md-9 .col-md-push-3

.col-md-3 .col-md-pull-9

<div class="row">
  <div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
  <div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
</div>

All page content should be wrapped by a single div with the .content class. This ensures the footer will stick to the bottom of the page if the page content is shorter then the viewport.

NOTE: The navbar and the footer should be outside with content wrapper.

<div class="body">
  <nav class="navbar">...</nav>
  <div class="content">...</div>
  <footer>...</footer>
</div>

Fonts

Lato

By default all World Vision content is displayed in 'Lato' with fallbacks of 'Trebuchet MS' and 'Arial'.

Beacon heading

The beacon heading is a h1 that is used as a primary page heading. It comes in a few variants.

The default beacon heading can be used with a full sentence.

The H1 beacon heading used with a full sentence.


<div class="beacon">
  <h1>...</h1>
</div>

A larger version of the beacon heading can be used in a heading with a maximum of 2 words.

Beacon Large


<div class="beacon bacon-lg">
  <h1>...</h1>
</div>

Both versions of the beacon can have white text for display over images.

Beacon Large


<div class="beacon beacon-lg baecon-inverse">
  <h1>...</h1>
</div>

Beacon headings can also be displayed vertical center in their bounding element for use on a hero image.

If your centered beacon is on a hero shot that displays behind the navbar you can offset the text by adding the class .beacon-hero. NOTE: This offset is already set if the body tag contains the class .no-padding.

Beacon Large


<h1 class="beacon beacon-lg beacon-center">...</h1>

Type headings

All HTML headings, <h1> through <h6> are available. All headings use the Black variant of Lato and the H1 is in uppercase.

h1. Lato	Black ~64px
h2. Lato	Black ~45px
h3. Lato	Black ~32px
h4. Lato	Black ~22px
h5. Lato	Black ~16px
h6. Lato	Black ~11px


<h1>...</h1>
<h2>...</h2>
<h3>...</h3>
<h4>...</h4>
<h5>...</h5>
<h6>...</h6>

Body copy

WVA's global default font-size is 16px, with a line-height of 1.45. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their computed line-height (10px by default).

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.

Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec ullamcorper nulla non metus auctor fringilla. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec ullamcorper nulla non metus auctor fringilla.

Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit.

<p>...</p>

Lead body copy

Make a paragraph stand out by adding .lead.

Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.

<p class="lead">...</p>

Emphasis

Make use of HTML's default emphasis tags with lightweight styles.

Small text

For de-emphasizing inline or blocks of text, use the <small> tag to set text at 85% the size of the parent. Heading elements receive their own font-size for nested <small> elements.

This line of text is meant to be treated as fine print.

<small>This line of text is meant to be treated as fine print.</small>

Bold

For emphasizing a snippet of text with a heavier font-weight.

The following snippet of text is rendered as bold text.

<strong>rendered as bold text</strong>

Italics

For emphasizing a snippet of text with italics.

The following snippet of text is rendered as italicized text.

<em>rendered as italicized text</em>

Alternate elements

Feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.

Alignment classes

Easily realign text to components with text alignment classes.

Left aligned text.

Center aligned text.

Right aligned text.

<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>

Emphasis classes

Convey meaning through color with a handful of emphasis utility classes.

Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.

Basic abbreviation

For expanded text on long hover of an abbreviation, include the title attribute with the <abbr> element.

An abbreviation of the word attribute is attr.

<abbr title="attribute">attr</abbr>

Initialism

Add .initialism to an abbreviation for a slightly smaller font-size.

HTML is the best thing since sliced bread.

<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>

Addresses

Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <br>.

Twitter, Inc.

Blockquotes

For quoting blocks of content from another source within your document.

Default blockquote

Wrap <blockquote> around any HTML as the quote. For straight quotes, we recommend a <p>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>

Blockquote options

Style and content changes for simple variations on a standard <blockquote>.

Naming a source

Add <small> tag for identifying the source. Wrap the name of the source work in <cite>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
Someone famousSource Title

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <small>Someone famous<cite title="Source Title">Source Title</cite></small>
</blockquote>

Alternate displays

Use .pull-right for a floated, right-aligned blockquote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
Someone famousSource Title

<blockquote class="pull-right">
  ...
</blockquote>

Lists

Unordered

A list of items in which the order does not explicitly matter.

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem
- Ac tristique libero volutpat at
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ul>
  <li>...</li>
</ul>

Ordered

A list of items in which the order does explicitly matter.

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ol>
  <li>...</li>
</ol>

Unstyled

Remove the default list-style and left margin on list items (immediate children only). This only applies to immediate children list items, meaning you will need to add the class for any nested lists as well.

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem
- Ac tristique libero volutpat at
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ul class="list-unstyled">
  <li>...</li>
</ul>

Inline

Place all list items on a single line with display: inline-block; and some light padding.

Lorem ipsum
Phasellus iaculis
Nulla volutpat

<ul class="list-inline">
  <li>...</li>
</ul>

Description

A list of terms with their associated descriptions.

Description lists: A description list is perfect for defining terms.
Euismod: Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.; Donec id elit non mi porta gravida at eget metus.
Malesuada porta: Etiam porta sem malesuada magna mollis euismod.

<dl>
  <dt>...</dt>
  <dd>...</dd>
</dl>

Horizontal description

Make terms and descriptions in <dl> line up side-by-side. Starts off stacked like default <dl>s, but when the navbar expands, so do these.

Description lists: A description list is perfect for defining terms.
Euismod: Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.; Donec id elit non mi porta gravida at eget metus.
Malesuada porta: Etiam porta sem malesuada magna mollis euismod.
Felis euismod semper eget lacinia: Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.

<dl class="dl-horizontal">
  <dt>...</dt>
  <dd>...</dd>
</dl>

Auto-truncating

Horizontal description lists will truncate terms that are too long to fit in the left column with text-overflow. In narrower viewports, they will change to the default stacked layout.

Inline

Wrap inline snippets of code with <code>.

For example, <section> should be wrapped as inline.

For example, <code>&lt;section&gt;</code> should be wrapped as inline.

Basic block

Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.

<p>Sample text here...</p>

<pre>&lt;p&gt;Sample text here...&lt;/p&gt;</pre>

You may optionally add the .pre-scrollable class, which will set a max-height of 350px and provide a y-axis scrollbar.

Basic example

For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>. It may seem super redundant, but given the widespread use of tables for other plugins like calendars and date pickers, we've opted to isolate our custom table styles.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table">
  ...
</table>

Striped rows

Use .table-striped to add zebra-striping to any table row within the <tbody>.

Cross-browser compatibility

Striped tables are styled via the :nth-child CSS selector, which is not available in Internet Explorer 8.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table table-striped">
  ...
</table>

Bordered table

Add .table-bordered for borders on all sides of the table and cells.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
1	Mark	Otto	@TwBootstrap
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-bordered">
  ...
</table>

Hover rows

Add .table-hover to enable a hover state on table rows within a <tbody>.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-hover">
  ...
</table>

Condensed table

Add .table-condensed to make tables more compact by cutting cell padding in half.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-condensed">
  ...
</table>

Contextual classes

Use contextual classes to color table rows or individual cells.

Class	Description
`.active`	Applies the hover color to a particular row or cell
`.success`	Indicates a successful or positive action
`.warning`	Indicates a warning that might need attention
`.danger`	Indicates a dangerous or potentially negative action

#	Column heading	Column heading	Column heading
1	Column content	Column content	Column content
2	Column content	Column content	Column content
3	Column content	Column content	Column content
4	Column content	Column content	Column content
5	Column content	Column content	Column content
6	Column content	Column content	Column content
7	Column content	Column content	Column content

<!-- On rows -->
<tr class="active">...</tr>
<tr class="success">...</tr>
<tr class="warning">...</tr>
<tr class="danger">...</tr>

<!-- On cells (`td` or `th`) -->
<tr>
  <td class="active">...</td>
  <td class="success">...</td>
  <td class="warning">...</td>
  <td class="danger">...</td>
</tr>

Responsive tables

Create responsive tables by wrapping any .table in .table-responsive to make them scroll horizontally up to small devices (under 768px). When viewing on anything larger than 768px wide, you will not see any difference in these tables.

#	Table heading	Table heading	Table heading	Table heading	Table heading	Table heading
1	Table cell	Table cell	Table cell	Table cell	Table cell	Table cell
2	Table cell	Table cell	Table cell	Table cell	Table cell	Table cell
3	Table cell	Table cell	Table cell	Table cell	Table cell	Table cell

#	Table heading	Table heading	Table heading	Table heading	Table heading	Table heading

2	Table cell	Table cell	Table cell	Table cell	Table cell	Table cell
3	Table cell	Table cell	Table cell	Table cell	Table cell	Table cell

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Basic example

Individual form controls automatically receive some global styling. All textual <input>, <textarea>, and <select> elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

<form role="form">
  <div class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
  </div>
  <div class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
    <p class="help-block">Example block-level help text here.</p>
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Check me out
    </label>
  </div>
  <button type="submit" class="btn btn-default">Submit</button>
</form>

Inline form

Add .form-inline for left-aligned and inline-block controls for a compact layout.

Requires custom widths

Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.

Always add labels

Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only class.

<form class="form-inline" role="form">
  <div class="form-group">
    <label class="sr-only" for="exampleInputEmail2">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email">
  </div>
  <div class="form-group">
    <label class="sr-only" for="exampleInputPassword2">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password">
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Remember me
    </label>
  </div>
  <button type="submit" class="btn btn-default">Sign in</button>
</form>

Horizontal form

Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form. Doing so changes .form-groups to behave as grid rows, so no need for .row.

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label for="inputEmail1" class="col-lg-2 control-label">Email</label>
    <div class="col-lg-10">
      <input type="email" class="form-control" id="inputEmail1" placeholder="Email">
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword1" class="col-lg-2 control-label">Password</label>
    <div class="col-lg-10">
      <input type="password" class="form-control" id="inputPassword1" placeholder="Password">
    </div>
  </div>
  <div class="form-group">
    <div class="col-lg-offset-2 col-lg-10">
      <div class="checkbox">
        <label>
          <input type="checkbox"> Remember me
        </label>
      </div>
    </div>
  </div>
  <div class="form-group">
    <div class="col-lg-offset-2 col-lg-10">
      <button type="submit" class="btn btn-default">Sign in</button>
    </div>
  </div>
</form>

Supported controls

Examples of standard form controls supported in an example form layout.

Inputs

Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.

Type declaration required

Inputs will only be fully styled if their type is properly declared.

<input type="text" class="form-control" placeholder="Text input">

File Input

Styling a file input button with CSS does not work natively across all browsers, so we have implemented a JS solution.

To allow for a styled file input, first give your file input a class of file-upload. Next precede the input element with a new div with the class dummy-file. Inside this div you will need to create an empty span element that will display the selected file, as well as the new upload button.

Click the button below and select a file to see how it works

<div class="dummy-file"><div class="btn btn-primary">Upload file</div><span>Please select a file</span></div>
<div class="file-input-wrapper"><input class="file-upload" type="file"></div>

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.

<textarea class="form-control" rows="3"></textarea>

Checkboxes and radios

Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.

Default (stacked)

<div class="checkbox">
  <label>
    <input type="checkbox" value="">
    Option one is this and that&mdash;be sure to include why it's great
  </label>
</div>

<div class="radio">
  <label>
    <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
    Option one is this and that&mdash;be sure to include why it's great
  </label>
</div>
<div class="radio">
  <label>
    <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
    Option two can be something else and selecting it will deselect option one
  </label>
</div>

      <label class="checkbox-styled">
        <input type="checkbox" disabled/>
        <span>Checked disabled checkbox</span>
        </label>

Inline checkboxes

Use .checkbox-inline or .radio-inline class to a series of checkboxes or radios for controls appear on the same line.

<label class="checkbox-inline">
  <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox-inline">
  <input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox-inline">
  <input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>

Selects

Use the default option, or add multiple to show multiple options at once.

<select class="form-control">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

<select multiple class="form-control">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

Static control

When you need to place plain text next to a form label within a horizontal form, use the .form-control-static class on a <p>.

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label class="col-lg-2 control-label">Email</label>
    <div class="col-lg-10">
      <p class="form-control-static">email@example.com</p>
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword" class="col-lg-2 control-label">Password</label>
    <div class="col-lg-10">
      <input type="password" class="form-control" id="inputPassword" placeholder="Password">
    </div>
  </div>
</form>

Form states

Provide feedback to users or visitors with basic feedback states on form controls and labels.

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.

<input class="form-control" id="focusedInput" type="text" value="This is focused...">

Disabled inputs

Add the disabled attribute on an input to prevent user input and trigger a slightly different look.

<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Disabled fieldsets

Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once.

Link functionality of `<a>` not impacted

This class will only change the appearance of <a class="btn btn-default"> buttons, not their functionality. Use custom JavaScript to disable links here.

Cross-browser compatibility

While Bootstrap will apply these styles in all browsers, Internet Explorer 9 and below don't actually support the disabled attribute on a <fieldset>. Use custom JavaScript to disable the fieldset in these browsers.

<form class="form-inline" role="form">
  <fieldset disabled>
    <div class="form-group">
      <label for="disabledTextInput">Disabled input</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
    </div>
    <div class="form-group">
      <label for="disabledSelect">Disabled select menu</label>
      <select id="disabledSelect" class="form-control">
        <option>Disabled select</option>
      </select>
    </div>
    <div class="checkbox">
      <label>
        <input type="checkbox"> Can't check this
      </label>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </fieldset>
</form>

Validation states

Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.

<div class="form-group has-success">
  <label class="control-label" for="inputSuccess">Input with success</label>
  <input type="text" class="form-control" id="inputSuccess">
</div>
<div class="form-group has-warning">
  <label class="control-label" for="inputWarning">Input with warning</label>
  <input type="text" class="form-control" id="inputWarning">
</div>
<div class="form-group has-error">
  <label class="control-label" for="inputError">Input with error</label>
  <input type="text" class="form-control" id="inputError">
</div>

Control sizing

Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.

Height sizing

Create larger or smaller form controls that match button sizes.

<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">

<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>

Column sizing

Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.

<div class="row">
  <div class="col-lg-2">
    <input type="text" class="form-control" placeholder=".col-lg-2">
  </div>
  <div class="col-lg-3">
    <input type="text" class="form-control" placeholder=".col-lg-3">
  </div>
  <div class="col-lg-4">
    <input type="text" class="form-control" placeholder=".col-lg-4">
  </div>
</div>

Help text

Block level help text for form controls.

<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>

Options

Use any of the available button classes to quickly create a styled button.

<!-- Standard gray button with gradient -->
<button type="button" class="btn btn-default">Default</button>

<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">Primary</button>

<!-- Identifies the secondary action in a set of buttons -->
<button type="button" class="btn btn-secondary">Secondary</button>

<!-- Indicates a CTA or successful/positive action -->
<button type="button" class="btn btn-success">Success</button>

<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">Info</button>

<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning">Warning</button>

<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger">Danger</button>

<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">Link</button>

<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-secondary-link">Link two</button>

Sizes

Fancy larger or smaller buttons? Add .btn-xl, .btn-lg, .btn-sm, or .btn-xs for additional sizes.

<p>
  <button type="button" class="btn btn-primary btn-lg">Large button</button>
  <button type="button" class="btn btn-default btn-lg">Large button</button>
</p>
<p>
  <button type="button" class="btn btn-primary">Default button</button>
  <button type="button" class="btn btn-default">Default button</button>
</p>
<p>
  <button type="button" class="btn btn-primary btn-sm">Small button</button>
  <button type="button" class="btn btn-default btn-sm">Small button</button>
</p>
<p>
  <button type="button" class="btn btn-primary btn-xs">Extra small button</button>
  <button type="button" class="btn btn-default btn-xs">Extra small button</button>
</p>

Create block level buttons—those that span the full width of a parent— by adding .btn-block.

<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>

Active state

Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. For <button> elements, this is done via :active. For <a> elements, it's done with .active. However, you may use .active on <button>s should you need to replicate the active state progammatically.

Button element

No need to add :active as it's a pseudo-class, but if you need to force the same appearance, go ahead and add .active.

<button type="button" class="btn btn-primary btn-lg active">Primary button</button>
<button type="button" class="btn btn-default btn-lg active">Button</button>

Anchor element

Add the .active class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-primary btn-lg active" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg active" role="button">Link</a>

Disabled state

Make buttons look unclickable by fading them back 75%.

Button element

Add the disabled attribute to <button> buttons.

<button type="button" class="btn btn-lg btn-primary" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-default btn-lg" disabled="disabled">Button</button>

Cross-browser compatibility

If you add the disabled attribute to a <button>, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.

Anchor element

Add the .disabled class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-primary btn-lg disabled">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled">Link</a>

We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.

Link functionality not impacted

This class will only change the <a>'s appearance, not its functionality. Use custom JavaScript to disable links here.

Button tags

Use the button classes on an <a>, <button>, or <input> element.

<a class="btn btn-default" href="#">Link</a>
<button class="btn btn-default" type="submit">Button</button>
<input class="btn btn-default" type="button" value="Input">
<input class="btn btn-default" type="submit" value="Submit">

Cross-browser rendering

As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.

Among other things, there's a Firefox bug that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox.

Responsive images

Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%; and height: auto; to the image so that it scales nicely to the parent element.

<img src="..." class="img-responsive" alt="Responsive image">

Image shapes

Add classes to an <img> element to easily style images in any project.

Cross-browser compatibility

Keep in mind that Internet Explorer 8 lacks support for rounded corners.

A generic square placeholder image with rounded corners

A generic square placeholder image where only the portion within the circle circumscribed about said square is visible

A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera

<img src="..." alt="..." class="img-rounded">
<img src="..." alt="..." class="img-circle">
<img src="..." alt="..." class="img-thumbnail">

Image captions

Add a blockquote with the class .caption directly after any image to create a caption for the media element. NOTE: This also works with iframes for video captions.

A generic square placeholder image with a caption

Hi, I'm a caption! I work best when the image
is contained within a grid column, that way I
will wrap perfectly.

<img src="..." alt="..." class="img-rounded">
<blockquote class="caption">...</blockquote>

Responsive video

By default, embedded Youtube and Vimeo videos do not have responsive functionality. You can add this functionality to any video by wrapping the Youtube or Vimeo iframe in a div with the .video-responsive class. This will apply some CSS to the iframe so that it scales nicely to the parent element.


<div class="video-responsive">
    <iframe width="..." height="..."  src="..."></iframe>
</div>

Contextual colors

Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.

Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>

Dealing with specificity

Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span> with the class.

Contextual backgrounds

Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

Nullam id dolor id nibh ultricies vehicula ut id elit.

<p class="bg-primary">...</p>
<p class="bg-success">...</p>
<p class="bg-info">...</p>
<p class="bg-warning">...</p>
<p class="bg-danger">...</p>
<p class="bg-web-gray">...</p>
<p class="bg-deep-gray">...</p>
<p class="bg-yellow">...</p>
<p class="bg-burnt-orange">...</p>
<p class="bg-pink">...</p>

<p class="bg-deep-blue">...</p>
<p class="bg-teal">...</p>
<p class="bg-khaki">...</p>
<p class="bg-light-green">...</p>

Close icon

Use the generic close icon for dismissing content like modals and alerts.

<button type="button" class="close" aria-hidden="true">&times;</button>

Margins and padding

Adjust padding and margins with these helper classes

Available in 0, 10, 20 and 50 for padding and margins in every direction.

Margin bottom 10px and Margin top 0px

Padding right 50pxMargin left 20px

Margin top 20px


<p class="margin-bottom-10 padding-top-0">Margin top 10px and Padding top 0px</p>
<p><span class="margin-right-50">Padding right 50px</span><span class="margin-left-20">Margin left 20px</span></p>
<p class="margin-top-20">Margin top 20px</p>

Quick floats

Float an element to the left or right with a class. !important is included to avoid specificity issues. Classes can also be used as mixins.

<div class="pull-left">...</div>
<div class="pull-right">...</div>

// Classes
.pull-left {
  float: left !important;
}
.pull-right {
  float: right !important;
}

// Usage as mixins
.element {
  .pull-left();
}
.another-element {
  .pull-right();
}

Not for use in navbars

To align components in navbars with utility classes, use .navbar-left or .navbar-right instead. See the navbar docs for details.

Center content blocks

Set an element to display: block and center via margin. Available as a mixin and class.

<div class="center-block">...</div>

// Classes
.center-block {
  display: block;
  margin-left: auto;
  margin-right: auto;
}

// Usage as mixins
.element {
  .center-block();
}

Clearfix

Clear the float on any element with the .clearfix class. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.

<!-- Usage as a class -->
<div class="clearfix">...</div>

// Mixin itself
.clearfix() {
  &:before,
  &:after {
    content: " ";
    display: table;
  }
  &:after {
    clear: both;
  }
}

// Usage as a Mixin
.element {
  .clearfix();
}

Showing and hiding content

Force an element to be shown or hidden (including for screen readers) with the use of .show and .hidden classes. These classes use !important to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins.

.hide is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden or .sr-only instead.

Furthermore, .invisible can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

<div class="show">...</div>
<div class="hidden">...</div>

// Classes
.show {
  display: block !important;
}
.hidden {
  display: none !important;
  visibility: hidden !important;
}
.invisible {
  visibility: hidden;
}

// Usage as mixins
.element {
  .show();
}
.another-element {
  .hidden();
}

Screen reader content

Hide an element to all devices except screen readers with .sr-only. Necessary for following accessibility best practices. Can also be used as a mixin.

<a class="sr-only" href="#content">Skip to main content</a>

// Usage as a Mixin
.skip-navigation {
  .sr-only();
}

Image replacement

Utilize the .text-hide class or mixin to help replace an element's text content with a background image.

<h1 class="text-hide">Custom heading</h1>

// Usage as a Mixin
.heading {
  .text-hide();
}

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.

Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities are currently only available for block and table toggling. Use with inline and table elements is currently not supported.

Available classes

Use a single or combination of the available classes for toggling content across viewport breakpoints.

	Extra small devices Phones (<768px)	Small devices Tablets (≥768px)	Medium devices Desktops (≥992px)	Large devices Desktops (≥1200px)
`.visible-xs`	Visible	Hidden	Hidden	Hidden
`.visible-sm`	Hidden	Visible	Hidden	Hidden
`.visible-md`	Hidden	Hidden	Visible	Hidden
`.visible-lg`	Hidden	Hidden	Hidden	Visible
`.hidden-xs`	Hidden	Visible	Visible	Visible
`.hidden-sm`	Visible	Hidden	Visible	Visible
`.hidden-md`	Visible	Visible	Hidden	Visible
`.hidden-lg`	Visible	Visible	Visible	Hidden

Print classes

Similar to the regular responsive classes, use these for toggling content for print.

Class	Browser	Print
`.visible-print`	Hidden	Visible
`.hidden-print`	Visible	Hidden

Test cases

Resize your browser or load on different devices to test the responsive utility classes.
