<!-- BUILT WITH LESS
================================================== -->

</div>
<img style="float: right; height: 36px; margin: 10px 20px 20px" src="assets/img/less-logo-large.png" alt="LESS CSS">
<p class="lead">{{_i}}Bootstrap is made with LESS at its core, a dynamic stylesheet language created by our good friend, <a href="http://cloudhead.io">Alexis Sellier</a>. It makes developing systems-based CSS faster, easier, and more fun.{{/i}}</p>
<h3>{{_i}}Why LESS?{{/i}}</h3>
<p>{{_i}}One of Bootstrap's creators wrote a quick <a href="http://www.wordsbyf.at/2012/03/08/why-less/">blog post about this</a>, summarized here:{{/i}}</p>
<ul>
<li>{{_i}}Bootstrap compiles faster ~6x faster with Less compared to Sass{{/i}}</li>
<li>{{_i}}Less is written in JavaScript, making it easier to us to dive in and patch compared to Ruby with Sass.{{/i}}</li>
<li>{{_i}}Less is more; we want to feel like we're writing CSS and making Bootstrap approachable to all.{{/i}}</li>
</ul>
<h3>{{_i}}What's included?{{/i}}</h3>
<p>{{_i}}As an extension of CSS, LESS includes variables, mixins for reusable snippets of code, operations for simple math, nesting, and even color functions.{{/i}}</p>
<h3>{{_i}}Learn more{{/i}}</h3>
<p>{{_i}}Visit the official website at <a href="http://lesscss.org">http://lesscss.org</a> to learn more.{{/i}}</p>

<!-- COMPILING LESS AND BOOTSTRAP
================================================== -->
<section id="compiling">
<div class="page-header">
<h1>{{_i}}Compiling Bootstrap with Less{{/i}}</h1>
</div>
<p class="lead">{{_i}}Since our CSS is written with Less and utilizes variables and mixins, it needs to be compiled for final production implementation. Here's how.{{/i}}</p>
<div class="alert alert-info">
{{_i}}<strong>Note:</strong> If you're submitting a pull request to GitHub with modified CSS, you <strong>must</strong> recompile the CSS via any of these methods.{{/i}}
</div>
<h2>{{_i}}Tools for compiling{{/i}}</h2>
<h3>{{_i}}Command line{{/i}}</h3>
<p>{{_i}}Follow <a href="https://github.com/twitter/bootstrap#developers">the instructions in the project readme</a> on GitHub for compiling via command line.{{/i}}</p>
<h3>{{_i}}JavaScript{{/i}}</h3>
<p>{{_i}}<a href="http://lesscss.org/">Download the latest Less.js</a> and include the path to it (and Bootstrap) in the <code><head></code>.{{/i}}</p>
<pre class="prettyprint">
<link rel="stylesheet/less" href="/path/to/bootstrap.less">
<script src="/path/to/less.js"></script>
</pre>
<p>{{_i}}To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.{{/i}}</p>
<h3>{{_i}}Unofficial Mac app{{/i}}</h3>
<p>{{_i}}<a href="http://incident57.com/less/">The unofficial Mac app</a> watches directories of .less files and compiles the code to local files after every save of a watched .less file. If you like, you can toggle preferences in the app for automatic minifying and which directory the compiled files end up in.{{/i}}</p>
<h3>{{_i}}More apps{{/i}}</h3>
<h4><a href="http://crunchapp.net/" target="_blank">Crunch</a></h4>
<p>{{_i}}Crunch is a great looking LESS editor and compiler built on Adobe Air.{{/i}}</p>
<h4><a href="http://incident57.com/codekit/" target="_blank">CodeKit</a></h4>
<p>{{_i}}Created by the same guy as the unofficial Mac app, CodeKit is a Mac app that compiles LESS, SASS, Stylus, and CoffeeScript.{{/i}}</p>
<h4><a href="http://wearekiss.com/simpless" target="_blank">Simpless</a></h4>
<p>{{_i}}Mac, Linux, and Windows app for drag and drop compiling of LESS files. Plus, the <a href="https://github.com/Paratron/SimpLESS" target="_blank">source code is on GitHub</a>.{{/i}}</p>
</section>
<!-- Static assets
================================================== -->
<section id="static-assets">
<div class="page-header">
<h1>{{_i}}Use as static assets{{/i}}</h1>
</div>
<p class="lead">{{_i}}<a href="./getting-started.html">Quickly start</a> any web project by dropping in the compiled or minified CSS and JS. Layer on custom styles separately for easy upgrades and maintenance moving forward.{{/i}}</p>
<h3>{{_i}}Setup file structure{{/i}}</h3>
<p>{{_i}}Download the latest compiled Bootstrap and place into your project. For example, you might have something like this:{{/i}}</p>
<pre>

<span class="icon-folder-open"></span> layouts/
<span class="icon-folder-open"></span> templates/
