Looking to contribute something to Bootstrap? **Here's how you can help.**
## Reporting issues
We only accept issues that are bug reports or feature requests. Bugs must be isolated and reproducible problems that we can fix within the Bootstrap core. Please read the following guidelines before opening any issue.
1.**Search for existing issues.** We get a lot of duplicate issues, and you'd help us out a lot by first checking if someone else has reported the same issue. Moreover, the issue may have already been resolved with a fix available.
2.**Create an isolated and reproducible test case.** Be sure the problem exists in Bootstrap's code with a [reduced test case](http://css-tricks.com/reduced-test-cases/) that should be included in each bug report.
3.**Include a live example.** Make use of jsFiddle or jsBin to share your isolated test cases.
4.**Share as much information as possible.** Include operating system and version, browser and version, version of Bootstrap, customized or vanilla build, etc. where appropriate. Also include steps to reproduce the bug.
## Key branches
-`master` is the latest, deployed version.
-`gh-pages` is the hosted docs (not to be used for pull requests).
-`*-wip` is the official work in progress branch for the next release.
## Pull requests
- Try to submit pull requests against the latest `*-wip` branch for easier merging
- CSS changes must be done in .less files first, never just the compiled files
- If modifying the .less files, always recompile and commit the compiled files bootstrap.css and bootstrap.min.css
- Try not to pollute your pull request with unintended changes--keep them simple and small
- Try to share which browsers your code has been tested in before submitting a pull request
## Coding standards
### HTML
- Two spaces for indentation, never tabs
- Double quotes only, never single quotes
- Always use proper indentation
- Use tags and elements appropriate for an HTML5 doctype (e.g., self-closing tags)
### CSS
- Adhere to the [Recess CSS property order](http://markdotto.com/2011/11/29/css-property-order/)
- Multiple-line approach (one property and value per line)
- Always a space after a property's colon (.e.g, `display: block;` and not `display:block;`)
- End all lines with a semi-colon
- For multiple, comma-separated selectors, place each selector on its own line
- Attribute selectors, like `input[type="text"]` should always wrap the attribute's value in double quotes, for consistency and safety (see this [blog post on unquoted attribute values](http://mathiasbynens.be/notes/unquoted-attribute-values) that can lead to XSS attacks).
### JS
- No semicolons
- Comma first
- 2 spaces (no tabs)
- strict mode
- "Attractive"
## License
By contributing your code, you agree to license your contribution under the terms of the APLv2: https://github.com/twbs/bootstrap/blob/master/LICENSE
Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created and maintained by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat).
To get started, check out [http://getbootstrap.com](http://getbootstrap.com)!
## Quick start
Three quick start options are available:
* [Download the latest release](https://github.com/twbs/bootstrap/zipball/3.0.0-wip).
* Clone the repo: `git clone git://github.com/twbs/bootstrap.git`.
* Install with [Bower](http://bower.io): `bower install bootstrap`.
Read the [Getting Started page](http://getbootstrap.com/getting-started/) for information on the framework contents, templates and examples, and more.
## Bugs and feature requests
Have a bug or a feature request? [Please open a new issue](https://github.com/twbs/bootstrap/issues). Before opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/).
## Documentation
Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](http://jekyllrb.com) and publicly hosted on GitHub Pages at [http://getbootstrap.com](http://getbootstrap.com). The docs may also be run locally.
### Running documentation locally
1. If necessary, [install Jekyll](http://jekyllrb.com/docs/installation) (requires v1.x).
2. From the root `/bootstrap` directory, run `jekyll serve` in the command line.
- **Windows users:** run `chcp 65001` first to change the command prompt's character encoding ([code page](http://en.wikipedia.org/wiki/Windows_code_page)) to UTF-8 so Jekyll runs without errors.
3. Open [http://localhost:9001](http://localhost:9001) in your browser, and voilà.
Learn more about using Jekyll by reading their [documentation](http://jekyllrb.com/docs/home/).
### Documentation for previous releases
Documentation for v2.3.2 has been made available for the time being at [http://getbootstrap.com/2.3.2/](http://getbootstrap.com/2.3.2/) while folks transition to Bootstrap 3.
[Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download.
## Compiling CSS and JavaScript
Bootstrap uses [Grunt](http://gruntjs.com/) with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.
### Install Grunt
From the command line:
1. Install `grunt-cli` globally with `npm install -g grunt-cli`.
2. Install the [necessary local dependencies](package.json) via `npm install`
When completed, you'll be able to run the various Grunt commands provided from the command line.
**Unfamiliar with `npm`? Don't have node installed?** That's a-okay. npm stands for [node packaged modules](http://npmjs.org/) and is a way to manage development dependencies through node.js. [Download and install node.js](http://nodejs.org/download/) before proceeding.
### Available Grunt commands
#### Build - `grunt`
Run `grunt` to run tests locally and compile the CSS and JavaScript into `/dist`. **Requires [recess](https://github.com/twitter/recess) and [uglify-js](https://github.com/mishoo/UglifyJS).**
#### Only compile CSS and JavaScript - `grunt dist`
`grunt dist` creates the `/dist` directory with compiled files. **Requires [recess](https://github.com/twitter/recess) and [uglify-js](https://github.com/mishoo/UglifyJS).**
#### Tests - `grunt test`
Runs jshint and qunit tests headlessly in [phantomjs](https://github.com/ariya/phantomjs/) (used for CI). **Requires [phantomjs](https://github.com/ariya/phantomjs/).**
#### Watch - `grunt watch`
This is a convenience method for watching just Less files and automatically building them whenever you save.
### Troubleshooting dependencies
Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun `npm install`.
## Contributing
Please read through our guidelines for contributing to Bootstrap. Included are directions for opening issues, coding standards, and notes on development.
More over, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the [Code Guide](http://github.com/mdo/code-guide), maintained by [Mark Otto](http://github.com/mdo).
Editor preferences are available in the [editor config](.editorconfig) for easy use in common text editors. Read more and download plugins at [http://editorconfig.org](http://editorconfig.org).
## Community
Keep track of development and community news.
* Follow [@twbootstrap on Twitter](http://twitter.com/twbootstrap).
* Read and subscribe to the [The Official Bootstrap Blog](http://blog.getbootstrap.com).
* Have a question that's not a feature request or bug report? [Ask on the mailing list.](http://groups.google.com/group/twitter-bootstrap)
* Chat with fellow Bootstrappers in IRC. On the `irc.freenode.net` server, in the `##twitter-bootstrap` channel.
## Versioning
For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible.
Releases will be numbered with the following format:
`<major>.<minor>.<patch>`
And constructed with the following guidelines:
* Breaking backward compatibility bumps the major (and resets the minor and patch)
* New additions without breaking backward compatibility bumps the minor (and resets the patch)
* Bug fixes and misc changes bumps the patch
For more information on SemVer, please visit [http://semver.org/](http://semver.org/).

<h3>Two columns with two nested columns</h3>
<p>Per the documentation, nesting is easy—just put a row of columns within an existing row. This gives you two columns <strong>starting at desktops and scaling to large desktops</strong>, with another two (equal widths) within the larger column.</p>
<p>At mobile device sizes, tablets and down, these columns and their nested columns will stack.</p>

<h3>Mixed: mobile and desktop</h3>
<p>The Bootstrap 3 grid system has four tiers of classes: xs (phones), sm (tablets), md (desktops), and lg (larger desktops). You can use nearly any combination of these classes to create more dynamic and flexible layouts.</p>
<p>Each tier of classes scales up, meaning if you plan on setting the same widths for xs and sm, you only need to specify xs.</p>

<pclass="lead">There are a few easy ways to quickly get started with Bootstrap, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.</p>
<h3>Download latest full source</h3>
<p>Until Bootstrap 3.0.0 is finalized, download the latest full source code (includes compiled and minified versions of our CSS and JavaScript under the <code>dist/</code> directory).</p>
<pclass="lead">The fastest way to get started is to get the compiled and minified versions of our CSS and JavaScript. No documentation or original source files are included.</p>
<p>Get the original files for all CSS and JavaScript by downloading the latest version directly from GitHub.</p>
<h4>
<ahref="{{ site.repo }}"onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'GitHub project']);">Clone or fork via GitHub</a>
</h4>
<p>Clone the entire project or fork your own version of Bootstrap to make it your own by visiting us on GitHub.</p>
<h4>
Install with <ahref="http://bower.io">Bower</a>
</h4>
<p>Install and manage the original files for all CSS and JavaScript, along with a local copy of the docs, using <ahref="http://bower.io">Bower</a>.</p>
<p>The folks over at <ahref="https://www.netdna.com/">NetDNA</a> have graciously provided CDN support for Bootstrap's CSS and JavaScript. To use, swap your local instances for the <ahref="http://www.bootstrapcdn.com/">Bootstrap CDN</a> links listed below.</p>
<p>If you download the original files, you need to compile Bootstrap's LESS files into usable CSS. To do that, Bootstrap only officially supports <ahref="http://twitter.github.io/recess/">Recess</a>, Twitter's CSS hinter built on top of <ahref="http://lesscss.org">less.js</a>.</p>
<pclass="lead">Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations.</p>
<p>Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:</p>
{% highlight bash %}
bootstrap/
├── css/
│ ├── bootstrap.css
│ ├── bootstrap.min.css
├── js/
│ ├── bootstrap.js
│ ├── bootstrap.min.js
{% endhighlight %}
<p>This is the most basic form of Bootstrap: compiled 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>).</p>
<divclass="bs-callout bs-callout-danger">
<h4>jQuery required</h4>
<p>Please note that <strong>all JavaScript plugins require jQuery</strong> to be included, as shown in the <ahref="#template">starter template</a>.</p>
<pclass="lead">Make use of a super basic HTML template, or dive into a <ahref="../getting-started#examples">few examples</a> we've started for you. We encourage folks to iterate on these examples and not simply use them as an end result.</p>
<p>Copy and paste the HTML from below to get started with a bare bones Bootstrap document.</p>
<pclass="lead">Build on the basic template above with Bootstrap's many components. Check out some of the more advanced tips for how to customize and build on top of them.</p>
<pclass="lead">Don't want your site or application to be scale on different device? With a little bit of work, you can disable the responsive features of Bootstrap so that mobile users see your full desktop-version site.</p>
<h3>Steps to disable responsive views</h3>
<p>To disable responsive features, follow these steps. See it in action in the modified template below.</p>
<ol>
<li>Remove (or just don't add) the viewport <code><meta></code> mentioned in <ahref="../css/#overview-mobile">the CSS docs</a></li>
<li>Force a single <code>max-width</code> on the <code>.container</code> (e.g., <code>.container { max-width: 940px; }</code>). Be sure that this comes after the default Bootstrap CSS; otherwise, you'll need <code>!important</code>.</li>
<li>For grid layouts, make use of <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 up to all resolutions, so you're set there.</li>
</ol>
<p>You'll still need respond.js for IE8 (since our media queries are still there and need to be picked up). This just disables the "mobile site" of Bootstrap.</p>
<h3>Bootstrap template with disabled responsive</h3>
<p>We've taken the above steps and applied them to a basic template here. Note the steps above are called out in comments here, e.g. <code><-- 1. --></code>.</p>
{% highlight html %}

<head>
<title>Disabling responsiveness in Bootstrap</title>
<pclass="lead">Bootstrap is built to work best in the latest desktop and mobile browsers, meaning older and less advanced browsers might receive a less stylized, though fully functional, version 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 Windows has more or less been discontinued)</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 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 many CSS3 properties—e.g., rounded corners and shadows—are not supported by IE8. The <code>placeholder</code> attribute is also not supported in either of these versions.</p>
<p>In addition, <strong>Internet Explorer 8 requires the use of <ahref="https://github.com/scottjehl/Respond">respond.js</a> to enable media query support.</strong></p>
<h3>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>
<p>See <ahref="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>Windows Phone 8 and Internet Explorer 10</h3>
<p>Internet Explorer 10 doesn't differentiate device width from viewport width, and thus doesn't properly apply the media queries in Bootstrap's CSS. To address this, you can optionally include the following CSS and JavaScript to work around this problem until Microsoft issues a fix.</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")
<p>For more information and usage guidelines, read <ahref="http://timkadlec.com/2013/01/windows-phone-8-and-device-width/">Windows Phone 8 and Device-Width</a>.</p>
<h3>Safari percent rounding</h3>
<p>In the latest Safari for Mac, its rendering engine has a little trouble with the long decimal places of our <code>.col-*-1</code> grid classes, meaning if you have 12 individual columns you'll notice they come up short compared to other rows of columns. There's not much we can do here (<ahref="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>Modals and mobile devices</h3>
<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>
<h3>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>
<pclass="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>Google Maps</h3>
<p>If you're using Google Maps on a Bootstrapped project, you might run into some display problems due to our use of <code>* { box-sizing: border-box; }</code>. Previously, you may have also ran into issues with the use of <code>max-width</code> on images. The following snippet should avoid all those problems.</p>
{% highlight css %}
/* Fix Google Maps canvas
*
* Wrap your Google Maps embed in a `.google-map-canvas` to reset Bootstrap's
* global `box-sizing` changes. You may optionally need to reset the `max-width`
* on images in case you've applied that anywhere else. (That shouldn't be as
* necessary with Bootstrap 3 though as that behavior is relegated to the
<pclass="lead">Bootstrap follows common web standards, and with minimal extra effort, can be used to create sites that are accessibile to those using <abbrtitle="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 content</code> link immediately after your opening <code><body></code> tag. <ahref="http://a11yproject.com/posts/skip-nav-links/">(read why)</a></p>
{% highlight html %}
<body>
<ahref="#content"class="sr-only">Skip to content</a>
<divclass="container"id="content">
The main page content.
</div>
</body>
{% endhighlight %}
<h3>Nested headers</h3>
<p>Another "gotcha" has to do with how you nest your <code><header></code> elements. <ahref="http://squizlabs.github.io/HTML_CodeSniffer/Standards/Section508/">Section 508</a> states that your largest header must be an <code>h1</code>, and the next header must be an <code><h2></code>, etc. This is hard to achieve in practice, but if the largest header on your site is smaller than Bootstrap's default 38px, you should consider modifying your stylesheets before using a smaller header element.</p>

<h1id="customizing">Customizing Bootstrap</h1>
</div>
<pclass="lead">Customizing Bootstrap is best accomplished when you treat it as another dependency in your development stack. Doing so ensures future upgrades are as easy as possible while also familiarizing yourself to the intricacies of the framework.</p>
<p>Once you've downloaded and included Bootstrap's CSS into your templates, you can move on to customizing the included components. To do so, create a new stylesheet (LESS, if you like, or just plain CSS) to house your customizations.</p>
<divclass="bs-callout bs-callout-info">
<h4>Compiled or minified?</h4>
<p>Unless you plan on reading a good chunk of the compiled CSS, go with the minified. It's the same code, just compacted. Less bandwidth is good, especially in production environments.</p>
</div>
<p>From there, include whatever Bootstrap components and HTML content you need to get your template setup. It's best to have a rough idea in mind of modifications to make and content to include, so be sure to spend a brief amount of time on that before moving on.</p>
<h3>Customizing components</h3>
<p>There are varying degrees to customizing components, but most fall into two camps: light customizations and complete visual overhauls. Luckily, there are plenty of examples of both.</p>
<p>We define light customizations as mostly surface layer changes, things like a color and font changes to existing Bootstrap components. A great example of this is the the <ahref="http://translate.twitter.com">Twitter Translation Center</a> (coded by @mdo). Let's look at how to implement the custom button we wrote for this site, <code>.btn-ttc</code>.</p>
<p>Instead of using the provided Bootstrap buttons, which only require just one class to start, <code>.btn</code>, we'll add our own modifier class, <code>.btn-ttc</code>. This will give us a slightly custom look with minimal effort.</p>
/* An easy hover state is just to move the gradient up a small amount. Add other embellishments as you see fit. */
.btn-ttc:hover {
background-position: 0 -15px;
}
{% endhighlight %}
<p>Customizing Bootstrap components takes time, but should be straightforward. <strong>Look to the source code often and duplicate the selectors you need for your modifications.</strong> Placing them after the Bootstrap source makes for easy overriding without complication. <strong>To recap, here's the basic workflow:</strong></p>
<ul>
<li>For each element you want to customize, find its code in the compiled Bootstrap CSS. Copy and paste the selector for a component as-is. For instance, to customize the navbar background, just snag <code>.navbar</code>.</li>
<li>Add all your custom CSS in a separate stylesheet using the selectors you just copied from the Bootstrap source. No need for prefacing with additional classes or using <code>!important</code> here.</li>
<li>Rinse and repeat until you're happy with your customizations.</li>
</ul>
<p>Going beyond light customizations and into visual overhauls is just as straightforward as the above custom button. For a site like <ahref="http://yourkarma.com">Karma</a>, which uses Bootstrap as a CSS reset with heavy modifications, more extensive work is involved, but well worth it in the end.</p>
<divclass="bs-callout bs-callout-info">
<h4>Alternate customization methods</h4>
<p>While not recommended for folks new to Bootstrap, you may use one of two alternate methods for customization. The first is modifying the source .less files (making upgrades super difficult), and the second is mapping source LESS code to <ahref="http://ruby.bvision.com/blog/please-stop-embedding-bootstrap-classes-in-your-html">your own classes via mixins</a>. For the time being, neither options are documented here.</p>
</div>
<h3>Removing potential bloat</h3>
<p>Not all sites and applications need to make use of everything Bootstrap has to offer, especially in production environments where bandwidth literally becomes a financial issue. We encourage folks to remove whatever is unused with our <ahref="../customize/">Customizer</a>.</p>
<p>Using the Customizer, simply uncheck any component, feature, or asset you don't need. Hit download and swap out the default Bootstrap files with these newly customized ones. You'll get vanilla Bootstrap, but without the features *you* deem unnecessary. All custom builds include compiled and minified versions, so use whichever works for you.</p>
