      <h1>Overview</h1>
    </div>
    <p class="lead">Get the lowdown on the key pieces of Bootstrap's infrastructure, including our approach to better, faster, stronger web development.</p>

    <h3 id="overview-doctype">HTML5 doctype required</h3>
    <p>Bootstrap makes use of certain HTML elements and CSS properties that require the use of the HTML5 doctype. Include it at the beginning of all your projects.</p>
{% highlight html %}
<!DOCTYPE html>
<html lang="en">
  ...
</html>
{% endhighlight %}

    <h3 id="overview-mobile">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>
{% highlight html %}
<meta name="viewport" content="width=device-width, initial-scale=1.0">
{% endhighlight %}

    <h3 id="overview-responsive-images">Responsive images</h3>
    <p>We automatically attempt to scale images to appropriate sizes with a global <code>max-width: 100%;</code> on all <code>&lt;img&gt;</code> elements. If you run into problems (e.g., with Google Maps), be sure to disable this property on a per-case basis.</p>

    <h3 id="overview-type-links">Typography and links</h3>
    <p>Bootstrap sets basic global display, typography, and link styles. Specifically, we:</p>
    <ul>
      <li>Remove <code>margin</code> on the body</li>
      <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>
    </ul>
    <p>These styles can be found within <strong>scaffolding.less</strong>.</p>

    <h3 id="overview-reset">Normalize reset</h3>
    <p>For improved cross-browser rendering, we use <a href="http://necolas.github.com/normalize.css/" target="_blank">Normalize</a>, a project by <a href="http://twitter.com/necolas" target="_blank">Nicolas Gallagher</a> and <a href="http://twitter.com/jon_neal" target="_blank">Jonathan Neal</a>.</p>

    <h3 id="overview-container">Centering with container</h3>
    <p>Easily center a page's contents by wrapping its contents in a container. Containers set `max-width` at various media query breakpoints to match our grid system.</p>

  <!-- Grid system
  ================================================== -->
  <div class="bs-docs-section" id="grid">
    <div class="page-header">
      <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-lg-*</code> elements within a <code>.row</code>. As this is a 12-column grid, each <code>.col-lg-*</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>
    <p>Be sure to checkout the <a href="../examples/grid/">full-page grid example</a> as well.</p>

</div>
{% endhighlight %}

    <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>

    <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>
{% highlight css %}
@grid-columns:              12;
@grid-gutter-width:         30px;
@grid-float-breakpoint:     768px;
{% endhighlight %}

    <h4>Mixins</h4>
    <p>Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.</p>
{% highlight css %}
// 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);
  // Then clear the floated columns
  .clearfix();
}

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

    <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>
{% highlight css %}
.wrapper {
  .make-row();
}
.content-main {
  .make-column(8);
}
.content-secondary {
  .make-column(3);
  .make-column-offset(1);
}
{% endhighlight %}
{% highlight html %}
<div class="wrapper">
  <div class="content-main">...</div>
  <div class="content-secondary">...</div>
</div>
{% endhighlight %}

    <!-- Body copy -->
    <h2 id="type-body-copy">Body copy</h2>
    <p>Bootstrap's global default <code>font-size</code> is <strong>14px</strong>, with a <code>line-height</code> of <strong>1.428</strong>. This is applied to the <code>&lt;body&gt;</code> and all paragraphs. In addition, <code>&lt;p&gt;</code> (paragraphs) receive a bottom margin of half their computed line-height (10px by default).</p>
    <div class="bs-example">
      <p>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.</p>
      <p>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.</p>
      <p>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>
    </div>
{% highlight html %}
<p>...</p>
{% endhighlight %}

    <!-- Body copy .lead -->
    <h3>Lead body copy</h3>
    <p>Make a paragraph stand out by adding <code>.lead</code>.</p>
    <div class="bs-example">
      <p class="lead">Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.</p>
    </div>
{% highlight html %}
<p class="lead">...</p>
{% endhighlight %}

    <!-- 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>


    <!-- Emphasis -->
    <h2 id="type-emphasis">Emphasis</h2>
    <p>Make use of HTML's default emphasis tags with lightweight styles.</p>

    <h3>Small text</h3>
    <p>For de-emphasizing inline or blocks of text, use the <code>&lt;small&gt;</code> tag to set text at 85% the size of the parent. Heading elements receive their own <code>font-size</code> for nested <code>&lt;small&gt;</code> elements.</p>
    <div class="bs-example">
      <p><small>This line of text is meant to be treated as fine print.</small></p>
    </div>
{% highlight html %}
<small>This line of text is meant to be treated as fine print.</small>
{% endhighlight %}


    <h3>Bold</h3>
    <p>For emphasizing a snippet of text with a heavier font-weight.</p>
    <div class="bs-example">
      <p>The following snippet of text is <strong>rendered as bold text</strong>.</p>
    </div>
{% highlight html %}
<strong>rendered as bold text</strong>
{% endhighlight %}

    <h3>Italics</h3>
    <p>For emphasizing a snippet of text with italics.</p>
    <div class="bs-example">
      <p>The following snippet of text is <em>rendered as italicized text</em>.</p>
    </div>
{% highlight html %}
<em>rendered as italicized text</em>
{% endhighlight %}

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

    <h3>Alignment classes</h3>
    <p>Easily realign text to components with text alignment classes.</p>
    <div class="bs-example">
      <p class="text-left">Left aligned text.</p>
      <p class="text-center">Center aligned text.</p>
      <p class="text-right">Right aligned text.</p>
    </div>
{% highlight html %}
<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>
{% endhighlight %}

    <h3>Emphasis classes</h3>
    <p>Convey meaning through color with a handful of emphasis utility classes.</p>
    <div class="bs-example">
      <p class="text-muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
      <p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
      <p class="text-danger">Donec ullamcorper nulla non metus auctor fringilla.</p>
      <p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
    </div>
{% highlight html %}
<p class="text-muted">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>
<p class="text-success">...</p>
{% endhighlight %}


    <!-- Abbreviations -->
    <h2 id="type-abbreviations">Abbreviations</h2>
    <p>Stylized implementation of HTML's <code>&lt;abbr&gt;</code> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a <code>title</code> attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.</p>

    <h3>Basic abbreviation</h3>
    <p>For expanded text on long hover of an abbreviation, include the <code>title</code> attribute with the <code>&lt;abbr&gt;</code> element.</p>
    <div class="bs-example">
      <p>An abbreviation of the word attribute is <abbr title="attribute">attr</abbr>.</p>
    </div>
{% highlight html %}
<abbr title="attribute">attr</abbr>
{% endhighlight %}

    <h3>Initialism</h3>
    <p>Add <code>.initialism</code> to an abbreviation for a slightly smaller font-size.</p>
    <div class="bs-example">
      <p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr> is the best thing since sliced bread.</p>
    </div>

    <h2 id="forms-control-states">Form control states</h2>
    <p>Provide feedback to users or visitors with basic feedback states on form controls and labels.</p>

    <h3 id="forms-input-focus">Input focus</h3>
    <p>We remove the default <code>outline</code> styles on some form controls and apply a <code>box-shadow</code> in its place for <code>:focus</code>.</p>
    <form class="bs-example">
      <input class="focused" id="focusedInput" type="text" value="This is focused...">
    </form>
{% highlight html %}

    <h3 id="forms-invalid-inputs">Invalid inputs</h3>
    <p>Style inputs via default browser functionality. Specify a <code>type</code>, add the <code>required</code> attribute if the field is not optional, and (if applicable) specify a <code>pattern</code>.</p>

    <div class="bs-callout">
      <h4>Cross-browser compatibility</h4>
      <p>Invalid inputs are styled via the <code>:invalid</code> CSS selector, which is not supported by Internet Explorer 9 and below.</p>
    </div>

    <form class="bs-example">
      <input type="email" placeholder="test@example.com" required>
    </form>
{% highlight html %}
<input type="email" placeholder="test@example.com" required>
{% endhighlight %}

    <h3 id="forms-disabled-inputs">Disabled inputs</h3>
    <p>Add the <code>disabled</code> attribute on an input to prevent user input and trigger a slightly different look.</p>
    <form class="bs-example">
      <input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here…" disabled>
    </form>
{% highlight html %}
<input id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
{% endhighlight %}

    <h3 id="forms-disabled-fieldsets">Disabled fieldsets</h3>
    <p>Add the <code>disabled</code> attribute to a <code>&lt;fieldset&gt;</code> to disable all the controls within the <code>&lt;fieldset&gt;</code> at once.</p>

    <div class="bs-callout">
      <h4>Link functionality of <code>&lt;a&gt;</code> not impacted</h4>
      <p>This class will only change the appearance of <code>&lt;a class="btn btn-default"&gt;</code> buttons, not their functionality. Use custom JavaScript to disable links here.</p>
    </div>

    <div class="bs-callout">
      <h4>Cross-browser compatibility</h4>
      <p>While Bootstrap will apply these styles in all browsers, IE and Safari don't actually support the <code>&lt;disabled&gt;</code> attribute on a <code>&lt;fieldset&gt;</code>. Use custom JavaScript to disable the fieldset in these browsers.</p>

    <h3 id="forms-validation">Validation states</h3>
    <p>Bootstrap includes validation styles for error, warning, info, and success messages. To use:</p>
    <ul>
      <li>Add <code>.has-warning</code>, <code>.has-error</code>, or <code>.has-success</code> to the parent element</li>
      <li>Add .input-with-feedback to the field(s) in question</li>
    </ul>
    <p>Validation styles are applied on a per-input basis. With horizontal forms, the <code>&lt;label class="control-label"&gt;</code> will always be styled.</p>

    <form class="bs-example form-horizontal">
      <div class="control-group has-warning">
        <label class="control-label" for="inputWarning">Input with warning</label>

    <p>Adding on top of existing browser controls, Bootstrap includes other useful form components.</p>

    <h3 id="forms-input-groups">Input groups</h3>
    <p>Add text or buttons before, after, or on both sides of any text-based input. Use <code>.input-group</code> with a <code>.add-on</code> to prepend or append elements to an <code>&lt;input&gt;</code>.</p>

    <div class="bs-callout">
      <h4>Cross-browser compatibility</h4>
      <p>Avoid using <code>&lt;select&gt;</code> elements here as they cannot be fully styled in WebKit browsers.</p>
    </div>

    <form class="bs-example">
      <div class="input-group col-lg-9">

    <h4>Buttons instead of text</h4>
    <p>Buttons in input groups are a bit different and require one extra level of nesting. Instead of <code>.input-group-addon</code>, you'll need to use <code>.input-group-btn</code> to wrap the buttons. This is required due to default browser styles that cannot be overridden.</p>
    <form class="bs-example">
      <div class="input-group col-lg-7">
        <span class="input-group-btn">

  <!-- Buttons
  ================================================== -->
  <div class="bs-docs-section" id="buttons">
    <div class="page-header">
      <h1>Buttons</h1>
    </div>

    <h2 id="buttons-options">Button options</h2>
    <p>Use any of the available button classes to quickly create a styled button.</p>
    <div class="bs-example">
      <button type="button" class="btn btn-default">Default</button>
      <button type="button" class="btn btn-primary">Primary</button>
      <button type="button" class="btn btn-success">Success</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>

<!-- Indicates a successful or 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 -->

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

    <h2 id="buttons-sizes">Button sizes</h2>
    <p>Fancy larger or smaller buttons? Add <code>.btn-large</code> or <code>.btn-small</code> for additional sizes.</p>
    <div class="bs-example">
      <p>
        <button type="button" class="btn btn-primary btn-large">Large button</button>
        <button type="button" class="btn btn-default btn-large">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-small">Small button</button>
        <button type="button" class="btn btn-default btn-small">Small button</button>
      </p>
    </div>
{% highlight html %}
<p>
  <button type="button" class="btn btn-primary btn-large">Large button</button>
  <button type="button" class="btn btn-default btn-large">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-small">Small button</button>
  <button type="button" class="btn btn-default btn-small">Small button</button>
</p>
{% endhighlight %}

    <p>Create block level buttons&mdash;those that span the full width of a parent&mdash; by adding <code>.btn-block</code>.</p>
    <div class="bs-example">
      <div class="well" style="max-width: 400px; margin: 0 auto 10px;">
        <button type="button" class="btn btn-primary btn-large btn-block">Block level button</button>
        <button type="button" class="btn btn-default btn-large btn-block">Block level button</button>
      </div>
    </div>
{% highlight html %}
<button type="button" class="btn btn-primary btn-large btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-large btn-block">Block level button</button>
{% endhighlight %}


    <h2 id="buttons-disabled">Disabled state</h2>
    <p>Make buttons look unclickable by fading them back 50%.</p>

    <h3>Button element</h3>
    <p>Add the <code>disabled</code> attribute to <code>&lt;button&gt;</code> buttons.</p>
    <p class="bs-example">
      <button type="button" class="btn btn-primary btn-large" disabled="disabled">Primary button</button>
      <button type="button" class="btn btn-default btn-large" disabled="disabled">Button</button>
    </p>
{% highlight html %}
<button type="button" class="btn btn-large btn-primary" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-default btn-large" disabled="disabled">Button</button>
{% endhighlight %}

    <div class="bs-callout">
      <h4>Cross-browser compatibility</h4>
      <p>If you add the <code>disabled</code> attribute to a <code>&lt;button&gt;</code>, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.</p>
    </div>

    <h3>Anchor element</h3>
    <p>Add the <code>.disabled</code> class to <code>&lt;a&gt;</code> buttons.</p>
    <p class="bs-example">
      <a href="#" class="btn btn-primary btn-large disabled">Primary link</a>
      <a href="#" class="btn btn-default btn-large disabled">Link</a>
    </p>
{% highlight html %}
<a href="#" class="btn btn-primary btn-large disabled">Primary link</a>
<a href="#" class="btn btn-default btn-large disabled">Link</a>
{% endhighlight %}
    <p>
      We use <code>.disabled</code> as a utility class here, similar to the common <code>.active</code> class, so no prefix is required.
    </p>
    <div class="bs-callout">
      <h4>Link functionality not impacted</h4>
      <p>This class will only change the <code>&lt;a&gt;</code>'s appearance, not its functionality. Use custom JavaScript to disable links here.</p>
    </div>


    <h2 id="buttons-tags">Using multiple tags</h2>
    <p>Use the button classes on an <code>&lt;a&gt;</code>, <code>&lt;button&gt;</code>, or <code>&lt;input&gt;</code> element.</p>
    <form class="bs-example">
      <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">
    </form>
{% highlight html %}
<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">
{% endhighlight %}

    <div class="bs-callout">
      <h4>Cross-browser rendering</h4>
      <p>As a best practice, <strong>we highly recommend using the <code>&lt;button&gt;</code> element whenever possible</strong> to ensure matching cross-browser rendering.</p>

    <h3>When to use</h3>
    <p>Use 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-level toggling, meaning <code>display: none;</code> or <code>display: block;</code>. Use with inline and table elements is currently not supported.</p>

    <h3>Test case</h3>
    <p>Resize your browser or load on different devices to test the responsive utility classes.</p>
    <h4>Visible on...</h4>
    <p>Green checkmarks indicate the element <strong>is visible</strong> in your current viewport.</p>
    <ul class="responsive-utilities-test visible-on">
