    <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>). The image files are compressed using <a href="http://imageoptim.com/">ImageOptim</a>, a Mac app for compressing PNGs.</p>
    <p>Please note that <strong>all JavaScript plugins require jQuery</strong> to be included.</p>

      <h1>Customizing Bootstrap</h1>
    </div>
198
    <p class="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>
199

200
    <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>
201

202
203
204
205
    <div class="bs-docs-sidenote">
      <p><strong>Compiled or minified?</strong></p>
      <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>
206

207
    <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>
208
209

    <h3>Customizing components</h3>
210
    <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>

241
242
243
244
245
246
247
    <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 <a href="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>
{% highlight html linenos %}
<button type="button" class="btn btn-ttc">Save changes</button>
{% endhighlight %}

  <p>In the custom stylesheet, add the following CSS:</p>

{% highlight css linenos %}
/* Custom button
-------------------------------------------------- */

/* Override base .btn styles */
/* Apply text and background changes to three key states: default, hover, and active (click). */
.btn-ttc,
.btn-ttc:hover,
.btn-ttc:active {
  color: white;
  text-shadow: 0 -1px 0 rgba(0, 0, 0, 0.25);
  background-color: #007da7;
}

/* Apply the custom-colored gradients */
/* Note: you'll need to include all the appropriate gradients for various browsers and standards. */
.btn-ttc {
  background-repeat: repeat-x;
  background-image: linear-gradient(top, #009ED2 0%, #007DA7 100%);
  ...
}

/* Set the hover state */
/* 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 %}

248
    <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>
249
250
251
252
253
    <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>
254
255
256
257
258
    <p>Going beyond light customizations and into visual overhauls is just as straightforward as the above custom button. For a site like <a href="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>

    <div class="bs-docs-sidenote">
      <p><strong>Side note:</strong> 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 <a href="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>
259
260

    <h3>Removing potential bloat</h3>
261
    <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 <a href="./customizer/">Customizer</a>.</p>
262
263
264
265
266
267
268
269
    <p>**img**</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>

    <h3>Mobile first</h3>
    <p>With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, <strong>Bootstrap is mobile first</strong>. Mobile first styles can be found throughout the entire library instead of in separate files.</p>
    <p>To ensure proper rendering and touch zooming, <strong>add the viewport meta tag</strong> to your <code>&lt;head&gt;</code>.</p>

      <li>Set <code>background-color: white;</code> on the <code>body</code></li>
      <li>Use the <code>@font-family-base</code>, <code>@font-size-base</code>, and <code>@line-height-base</code> attributes as our typographic base</li>
      <li>Set the global link color via <code>@link-color</code> and apply link underlines only on <code>:hover</code></li>

      <h1>Grid system</h1>
    </div>
    <p class="lead">Bootstrap includes a responsive, percent-based grid system that appropriately scales up to 12 columns as the device or viewport size increases&mdash;in other words, it's mobile first. It includes <a href="#grid-example">predefined classes</a> for this, as well as powerful <a href="#grid-less">mixins for generating semantic layouts</a>.</p>

    <h3 id="grid-example">Grid example</h3>
    <p>On mobile devices, the grid starts out stacked. Above 768px, it becomes horizontal as media queries kick in to apply <code>float</code>s and <code>width</code>s. To create a basic grid layout, wrap a series of <code>.col-span-*</code> elements within a <code>.row</code>. As this is a 12-column grid, each <code>.span*</code> spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent), even at mobile resolutions.</p>

    <h3 id="grid-less">LESS mixins and variables</h3>
    <p>In addition to <a href="#grid-example">prebuilt grid classes</a> for fast layouts, Bootstrap includes LESS variables and mixins for quickly generating your own simple, semantic layouts.</p>
448

449
450
    <h4>Variables</h4>
    <p>Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.</p>
451

{% highlight css linenos %}

@grid-gutter-width:         30px;
@grid-float-breakpoint:     768px;
{% endhighlight %}

457
458
    <h4>Mixins</h4>
    <p>Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.</p>
459

463
464

{% highlight css linenos %}
// Creates a wrapper for a series of columns
.make-row() {
  // Negative margin the row out to align the content of columns
  margin-left:  (@grid-gutter-width / -2);
  margin-right: (@grid-gutter-width / -2);

    // Calculate width based on number of columns available
    width: percentage(@columns / @grid-columns);
  }
  // Prevent columns from collapsing when empty
  min-height: 1px;
  // Set inner padding as gutters instead of margin
  padding-left:  (@grid-gutter-width / 2);
  padding-right: (@grid-gutter-width / 2);
}

// Generate the column offsets
.make-column-offset(@columns) {
  @media (min-width: @grid-float-breakpoint) {
    margin-left: percentage((@columns / @grid-columns));
  }
}
{% endhighlight %}

491
492
    <h4>Example usage</h4>
    <p>You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.</p>

    <!-- Using LESS -->
    <h3>Built with Less</h3>
    <p>The typographic scale is based on two LESS variables in <strong>variables.less</strong>: <code>@font-size-base</code> and <code>@line-height-base</code>. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.</p>
