<!-- Getting started
================================================== -->
<div class="bs-docs-section">
<div class="page-header">
<h1 id="download">Download Bootstrap</h1>
</div>
<p class="lead">Bootstrap has a few easy ways to quickly get started, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.</p>
<h3 id="download-compiled">Compiled CSS, JS, and fonts</h3>
<p>The fastest way to get Bootstrap is to download the precompiled and minified versions of our CSS, JavaScript, and fonts. No documentation or original source code files are included.</p>
<p><a class="btn btn-lg btn-primary" href="{{ site.download_dist }}" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'Download compiled']);" role="button">Download precompiled Bootstrap</a></p>
<h3 id="download-additional">Additional downloads</h3>
<div class="bs-docs-dl-options">
<h4>
<a href="{{ site.download_source }}" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'Download source']);">Download source code</a>
</h4>
<p>Get the latest Bootstrap LESS and JavaScript source code by downloading it directly from GitHub.</p>
<h4>
<a href="{{ site.repo }}" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'GitHub project']);">Clone or fork via GitHub</a>
</h4>
<p>Visit us on GitHub to clone or fork the Bootstrap project.</p>
<h4>
Install with <a href="http://bower.io">Bower</a>
</h4>
<p>Install and manage Bootstrap's styles, JavaScript, and documentation using <a href="http://bower.io">Bower</a>.</p>
{% highlight bash %}$ bower install bootstrap{% endhighlight %}
</div>
<h3 id="download-cdn">Bootstrap CDN</h3>
<p>The folks over at <a href="http://www.maxcdn.com/">MaxCDN</a> graciously provide CDN support for Bootstrap's CSS and JavaScript. Just use these <a href="http://www.bootstrapcdn.com/">Bootstrap CDN</a> links.</p>
{% highlight html %}
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="{{ site.cdn_css }}">
<!-- Optional theme -->
<link rel="stylesheet" href="{{ site.cdn_theme_css }}">
<!-- Latest compiled and minified JavaScript -->
<script src="{{ site.cdn_js }}"></script>
{% endhighlight %}
<div class="bs-callout bs-callout-warning" id="callout-less-compilation">
<h4>Compiling Bootstrap's LESS files</h4>
<p>If you work with Bootstrap's uncompiled source code, you need to compile the LESS files to produce usable CSS files. For compiling LESS files into CSS, we only officially support <a href="http://twitter.github.io/recess/">Recess</a>, which is Twitter's CSS hinter based on <a href="http://lesscss.org">less.js</a>.</p>
</div>
</div>
<!-- File structure
================================================== -->
<div class="bs-docs-section">
<div class="page-header">
<h1 id="whats-included">What's included</h1>
</div>
<p class="lead">Bootstrap is downloadable in two forms, within which you'll find the following directories and files, logically grouping common resources and providing both compiled and minified variations.</p>
<div class="bs-callout bs-callout-warning" id="jquery-required">
<h4>jQuery required</h4>
<p>Please note that <strong>all JavaScript plugins require jQuery</strong> to be included, as shown in the <a href="#template">starter template</a>. <a href="{{ site.repo }}/blob/v{{ site.current_version }}/bower.json">Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</p>
</div>
<h2 id="whats-included-precompiled">Precompiled Bootstrap</h2>
<p>Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:</p>
<!-- NOTE: This info is intentionally duplicated in the README.
Copy any changes made here over to the README too. -->
{% highlight bash %}
bootstrap/
├── css/
│ ├── bootstrap.css
│ ├── bootstrap.min.css
│ ├── bootstrap-theme.css
│ └── bootstrap-theme.min.css
├── js/
│ ├── bootstrap.js
│ └── bootstrap.min.js
└── fonts/
├── glyphicons-halflings-regular.eot
├── glyphicons-halflings-regular.svg
├── glyphicons-halflings-regular.ttf
└── glyphicons-halflings-regular.woff
{% endhighlight %}
<p>This is the most basic form of Bootstrap: precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (<code>bootstrap.*</code>), as well as compiled and minified CSS and JS (<code>bootstrap.min.*</code>). Fonts from Glyphicons are included, as is the optional Bootstrap theme.</p>
<h2 id="whats-included-source">Bootstrap source code</h2>
<p>The Bootstrap source code download includes the precompiled CSS, JavaScript, and font assets, along with source LESS, JavaScript, and documentation. More specifically, it includes the following and more:</p>
{% highlight bash %}
bootstrap/
├── less/
├── js/
├── fonts/
├── dist/
│ ├── css/
│ ├── js/
│ └── fonts/
├── docs-assets/
├── examples/
└── *.html
{% endhighlight %}
</div>
<p>The <code>less/</code>, <code>js/</code>, and <code>fonts/</code> are the source code for our CSS, JS, and icon fonts (respectively). The <code>dist/</code> folder includes everything listed in the precompiled download section above. <code>docs-assets/</code>, <code>examples/</code>, and all <code>*.html</code> files are for our documentation. Beyond that, any other included file provides support for packages, license information, and development.</p>
<!-- Template

</div>
<p class="lead">Start with this basic HTML template, or modify <a href="../getting-started#examples">these examples</a>. We hope you'll customize our templates and examples, adapting them to suit your needs.</p>

================================================== -->

<div class="page-header">
<h1 id="disable-responsive">Disabling responsiveness</h1>
</div>
<p class="lead">Bootstrap automatically adapts your pages for various screen sizes.
Here's how to disable this feature so your page works like in <a href="../examples/non-responsive/">this non-responsive example</a>.</p>
<h3>Steps to disable page responsiveness</h3>
<ol>
<li>Omit the viewport <code><meta></code> mentioned in <a href="../css/#overview-mobile">the CSS docs</a></li>
<li>Override the <code>width</code> on the <code>.container</code> for each grid tier with a single width, for example <code>width: 970px !important;</code> Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the <code>!important</code> with media queries or some selector-fu.</li>
<li>If using navbars, remove all navbar collapsing and expanding behavior.</li>
<li>For grid layouts, use <code>.col-xs-*</code> classes in addition to, or in place of, the medium/large ones. Don't worry, the extra-small device grid scales to all resolutions.</li>
</ol>
<p>You'll still need Respond.js for IE8 (since our media queries are still there and need to be processed).
This disables the "mobile site" aspects of Bootstrap.</p>
<h3>Bootstrap template with responsiveness disabled</h3>

<h2 id="migration-notes">Additional notes</h2>
<p>Other changes in v3.0 are not immediately apparent. Base classes, key styles, and behaviors have been adjusted for flexibility and our <em>mobile first</em> approach. Here's a partial list:</p>
<ul>
<li>By default, text-based form controls now receive only minimal styling. For focus colors and rounded corners, apply the <code>.form-control</code> class on the element to style.</li>
<li>Text-based form controls with the <code>.form-control</code> class applied are now 100% wide by default. Wrap inputs inside <code><div class="col-*"></div></code> to control input widths.</li>
<li><code>.badge</code> no longer has contextual (-success,-primary,etc..) classes.</li>
<li><code>.btn</code> must also use <code>.btn-default</code> to get the "default" button.</li>
<li><code>.container</code> and <code>.row</code> are now fluid (percentage-based).</li>
<li>Images are no longer responsive by default. Use <code>.img-responsive</code> for fluid <code><img></code> size.</li>
<li>The icons, now <code>.glyphicon</code>, are now font based. Icons also require a base and icon class (e.g. <code>.glyphicon .glyphicon-asterisk</code>).</li>
<li>Typeahead has been dropped, in favor of using <a href="http://twitter.github.io/typeahead.js/">Twitter Typeahead</a>.</li>
<li>Modal markup has changed significantly. The <code>.modal-header</code>, <code>.modal-body</code>, and <code>.modal-footer</code> sections are now wrapped in <code>.modal-content</code> and <code>.modal-dialog</code> for better mobile styling and behavior.</li>
<li>The HTML loaded by the <code>remote</code> modal option is now injected into the <code>.modal</code> instead of into the <code>.modal-body</code>. This allows you to also easily vary the header and footer of the modal, not just the modal body.</li>
<li>JavaScript events are namespaced. For example, to handle the modal "show" event, use <code>'show.bs.modal'</code>. For tabs "shown" use <code>'shown.bs.tab'</code>, etc.</li>
</ul>

<h1 id="browsers">Browser support</h1>
</div>
<p class="lead">Bootstrap is built to work best in the latest desktop and mobile browsers, meaning older browsers might display differently styled, though fully functional, renderings of certain components.</p>
<h3>Supported browsers</h3>
<p>Specifically, we support the latest versions of the following:</p>
<ul>
<li>Chrome (Mac, Windows, iOS, and Android)</li>
<li>Safari (Mac and iOS only, as the Windows version is being abandoned)</li>
<li>Firefox (Mac, Windows)</li>
<li>Internet Explorer</li>
<li>Opera (Mac, Windows)</li>
</ul>
<p>Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, Firefox for Linux, and Internet Explorer 7, though they are not officially supported.</p>
<h3>Internet Explorer 8 and 9</h3>
<p>Internet Explorer 8 and 9 are also supported, however, please be aware that some CSS3 properties and HTML5 elements are not fully supported by these browsers. In addition, <strong>Internet Explorer 8 requires the use of <a href="https://github.com/scottjehl/Respond">Respond.js</a> to enable media query support.</strong></p>

<h3>Internet Explorer 8 and Respond.js</h3>
<p>Beware of the following caveats when using Respond.js in your development and production environments for Internet Explorer 8.</p>
<h4 id="respond-js-x-domain">Respond.js and cross-domain CSS</h4>
<p>Using Respond.js with CSS hosted on a different (sub)domain (for example, on a CDN) requires some additional setup. <a href="https://github.com/scottjehl/Respond/blob/master/README.md#cdnx-domain-setup">See the Respond.js docs</a> for details.</p>
<h4 id="respond-file-proto">Respond.js and <code>file://</code></h4>
<p>Due to browser security rules, Respond.js doesn't work with pages viewed via the <code>file://</code> protocol (like when opening a local HTML file). To test responsive features in IE8, view your pages over HTTP(S). <a href="https://github.com/scottjehl/Respond/blob/master/README.md#support--caveats">See the Respond.js docs</a> for details.</p>
<h4 id="respond-import">Respond.js and <code>@import</code></h4>
<p>Respond.js doesn't work with CSS that's referenced via <code>@import</code>. In particular, some Drupal configurations are known to use <code>@import</code>. <a href="https://github.com/scottjehl/Respond/blob/master/README.md#support--caveats">See the Respond.js docs</a> for details.</p>
<h3>Internet Explorer 8 and box-sizing</h3>
<p>IE8 does not fully support <code>box-sizing: border-box;</code> when combined with <code>min-width</code>, <code>max-width</code>, <code>min-height</code>, or <code>max-height</code>. For that reason, as of v3.0.1, we no longer use <code>max-width</code> on <code>.container</code>s.</p>
<h3 id="ie-compat-modes">IE Compatibility modes</h3>
<p>Bootstrap is not supported in the old Internet Explorer compatibility modes. To be sure you're using the latest rendering mode for IE, consider including the appropriate <code><meta></code> tag in your pages:</p>
{% highlight html %}
<meta http-equiv="X-UA-Compatible" content="IE=edge">
{% endhighlight %}
<p>This tag is included in all docs pages and examples to ensure the best rendering possible in each supported version of Internet Explorer.</p>
<p>See <a href="http://stackoverflow.com/questions/6771258/whats-the-difference-if-meta-http-equiv-x-ua-compatible-content-ie-edge">this StackOverflow question</a> for more information.</p>
<h3 id="ie-10-width">Internet Explorer 10 in Windows 8 and Windows Phone 8</h3>
<p>Internet Explorer 10 doesn't differentiate <strong>device width</strong> from <strong>viewport width</strong>, and thus doesn't properly apply the media queries in Bootstrap's CSS. Normally you'd just add a quick snippet of CSS to fix this:</p>
{% highlight css %}
@-ms-viewport { width: device-width; }
{% endhighlight %}
<p>However, this doesn't work as it causes Windows Phone 8 devices to show a mostly desktop view instead of narrow "phone" view. To address this, you'll need to <strong>include the following CSS and JavaScript to work around the bug until Microsoft issues a fix</strong>.</p>
{% highlight css %}
@-webkit-viewport { width: device-width; }
@-moz-viewport { width: device-width; }
@-ms-viewport { width: device-width; }
@-o-viewport { width: device-width; }
@viewport { width: device-width; }
{% endhighlight %}
{% highlight js %}
if (navigator.userAgent.match(/IEMobile\/10\.0/)) {
var msViewportStyle = document.createElement("style")
msViewportStyle.appendChild(
document.createTextNode(
"@-ms-viewport{width:auto!important}"
)
)
document.getElementsByTagName("head")[0].appendChild(msViewportStyle)
}
{% endhighlight %}
<p>For more information and usage guidelines, read <a href="http://timkadlec.com/2013/01/windows-phone-8-and-device-width/">Windows Phone 8 and Device-Width</a>.</p>
<p>As a heads up, we include this in the Bootstrap docs as an example.</p>
<h3 id="safari-percentages">Safari percent rounding</h3>
<p>As of Safari v6.1 for OS X and Safari for iOS v7.0.1, Safari's rendering engine has some trouble with the number of decimal places used in our <code>.col-*-1</code> grid classes. So if you have 12 individual grid columns, you'll notice that they come up short compared to other rows of columns. We can't do much here (<a href="https://github.com/twbs/bootstrap/issues/9282">see #9282</a>) but you do have some options:</p>
<ul>
<li>Add <code>.pull-right</code> to your last grid column to get the hard-right alignment</li>
<li>Tweak your percentages manually to get the perfect rounding for Safari (more difficult than the first option)</li>
</ul>
<p>We'll keep an eye on this though and update our code if we have an easy solution.</p>
<h3 id="mobile-modals">Modals and mobile devices</h3>
<h4>Overflow and scrolling</h4>
<p>Support for <code>overflow: hidden</code> on the <code><body></code> element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the <code><body></code> content will begin to scroll.</p>
<h4>Virtual keyboards</h4>
<p>Also, note that if you're using inputs in your modal – iOS has a rendering bug that doesn't update the position of fixed elements when the virtual keyboard is triggered. A few workarounds for this include transforming your elements to <code>position: absolute</code> or invoking a timer on focus to try to correct the positioning manually. This is not handled by Bootstrap, so it is up to you to decide which solution is best for your application.</p>
<h3 id="browser-zoom">Browser zooming</h3>
<p>Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.</p>

<!-- Third party support
================================================== -->
<div class="bs-docs-section">
<div class="page-header">
<h1 id="third-parties">Third party support</h1>
</div>
<p class="lead">While we don't officially support any third party plugins or add-ons, we do offer some useful advice to help avoid potential issues in your projects.</p>
<h3>Box-sizing</h3>
<p>Some third party software, including Google Maps and Google Custom Search Engine, conflict with Bootstrap due to <code>* { box-sizing: border-box; }</code>, a rule which makes it so <code>padding</code> does not affect the final computed width of an element. Learn more about <a href="http://css-tricks.com/box-sizing/">box model and sizing at CSS Tricks</a>.</p>
<p>Depending on the context, you may override as-needed (Option 1) or reset the box-sizing for entire regions (Option 2).</p>
{% highlight css %}
/* Box-sizing resets
*
* Reset individual elements or override regions to avoid conflicts due to
* global box model settings of Bootstrap. Two options, individual overrides and
* region resets, are available as plain CSS and uncompiled LESS formats.
*/
/* Option 1A: Override a single element's box model via CSS */
.element {
-webkit-box-sizing: content-box;
-moz-box-sizing: content-box;
box-sizing: content-box;
}
/* Option 1B: Override a single element's box model by using a Bootstrap LESS mixin */
.element {
.box-sizing(content-box);

<p class="lead">Bootstrap follows common web standards, and with minimal extra effort, can be used to create sites that are accessible to those using <abbr title="Assistive Technology" class="initialism">AT</abbr>.</p>
<h3>Skip navigation</h3>
<p>If your navigation contains many links and comes before the main content in the DOM, add a <code>Skip to main content</code> link immediately after your opening <code><body></code> tag. <a href="http://a11yproject.com/posts/skip-nav-links/">(read why)</a></p>
{% highlight html %}
<body>
<a href="#content" class="sr-only">Skip to main content</a>
<div class="container" id="content">
The main page content.
</div>
</body>
{% endhighlight %}
<h3>Nested headings</h3>
<p>When nesting headings (<code><h1></code> - <code><h6></code>), your primary document header should be an <code><h1></code>. Subsequent headings should make logical use of <code><h2></code> - <code><h6></code> such that screen readers can construct a table of contents for your pages.</p>

<h1 id="customizing">Customizing Bootstrap</h1>
</div>
<p class="lead">Bootstrap is best maintained when you treat it as a separate and independently-versioned dependency in your development environment. Doing this makes upgrading Bootstrap easier in the future.</p>
<p>Once you've downloaded and included Bootstrap's styles and scripts, you can customize its components. Just create a new stylesheet (LESS, if you like, or just plain CSS) to house your customizations.</p>
<div class="bs-callout bs-callout-info">
<h4>Compiled or minified?</h4>
<p>Unless you plan on reading the CSS, go with minified stylesheets. It's the same code, just compacted. Minified styles use less bandwidth, which is good, especially in production environments.</p>
</div>
<p>From there, include whatever Bootstrap components and HTML content you need to create templates for your site's pages.</p>
<h3>Customizing components</h3>
<p>You can customize components to varying degrees, but most fall into two camps: <em>light customizations</em> and <em>overhauls</em>. Plenty examples of both are available from third parties.</p>
<p>We define <em>light customizations</em> as superficial changes, for example, color and font changes to existing Bootstrap components. A light customization example is the <a href="http://translate.twitter.com">Twitter Translation Center</a> (coded by <a href="https://twitter.com/mdo">@mdo</a>). Let's look at how to implement the custom button we wrote for this site, <code>.btn-ttc</code>.</p>
<p>The stock Bootstrap buttons require just one class, <code>.btn</code>, to start. Here we extend the <code>.btn</code> style with a new modifier class, <code>.btn-ttc</code>, that we will create. This gives us a distinct custom look with minimal effort.</p>
<p>Our customized button will be coded like this:</p>
{% highlight html %}
<button type="button" class="btn btn-ttc">Save changes</button>
{% endhighlight %}
<p>Note how <code>.btn-ttc</code> is added to the standard <code>.btn</code> class.</p>
<p>To implement this, in the custom stylesheet, add the following CSS:</p>
