<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>

+ <p>You can disable zooming capabilities on mobile devices by adding <code>user-scalable=no</code> to the viewport meta tag. This disables zooming, meaning users are only able to scroll, and results in your site feeling a bit more like a native application. Overall we don't recommend this on every site, so use caution!</p>

+ <p class="lead">Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes <a href="#grid-example-basic">predefined classes</a> for easy layout options, as well as powerful <a href="#grid-less">mixins for generating more semantic layouts</a>.</p>
+ <h3 id="grid-intro">Introduction</h3>
+ <p>Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:</p>
+ <ul>
+ <li>Rows must be placed within a <code>.container</code> for proper alignment and padding.</li>
+ <li>Use rows to create horizontal groups of columns.</li>
+ <li>Content should be placed within columns, and only columns may be immediate children of rows.</li>
+ <li>Predefined grid classes like <code>.row</code> and <code>.col-xs-4</code> are available for quickly making grid layouts. LESS mixins can also be used for more semantic layouts.</li>
+ <li>Columns create gutters (gaps between column content) via <code>padding</code>. That padding is offset in rows for the first and last column via negative margin on <code>.row</code>s.</li>
+ <li>Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three <code>.col-xs-4</code>.</li>
+ </ul>
+ <p>Look to the examples for applying these principles to your code.</p>

+ <h4>Grids and full-width layouts</h4>
+ <p>Folks looking to create fully fluid layouts (meaning your site stretches the entire width of the viewport) must wrap their grid content in a containing element with <code>padding: 0 15px;</code> to offset the <code>margin: 0 -15px;</code> used on <code>.row</code>s.</p>

+ <h3 id="grid-media-queries">Media queries</h3>
+ <p>We use the following media queries in our LESS files to create the key breakpoints in our grid system.</p>
+{% highlight css %}
+/* Extra small devices (phones, less than 768px) */
+/* No media query since this is the default in Bootstrap */
+
+/* Small devices (tablets, 768px and up) */
+@media (min-width: @screen-sm-min) { ... }
+
+/* Medium devices (desktops, 992px and up) */
+@media (min-width: @screen-md-min) { ... }
+
+/* Large devices (large desktops, 1200px and up) */
+@media (min-width: @screen-lg-min) { ... }
+{% endhighlight %}
+ <p>We occasionally expand on these media queries to include a <code>max-width</code> to limit CSS to a narrower set of devices.</p>
+{% highlight css %}
+@media (max-width: @screen-xs-max) { ... }
+@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... }

+ <p>Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any <code>.col-md-</code> class to an element will not only affect its styling on medium devices but also on large devices if a <code>.col-lg-</code> class is not present.</p>
<h3 id="grid-example-basic">Example: Stacked-to-horizontal</h3>
- <p>Using a single set of grid classes, you can create a basic grid system that starts out stacked on mobile and tablet devices before becoming horizontal on desktop devices.</p>

+ <h3 id="helper-classes-show-hide">Showing and hiding content</h3>
+ <p>Force an element to be shown or hidden (<strong>including for screen readers</strong>) with the use of <code>.show</code> and <code>.hidden</code> classes. These classes use <code>!important</code> to avoid specificity conflicts, just like the <a href="../css/#helper-classes-floats">quick floats</a>. They are only available for block level toggling. They can also be used as mixins.</p>
+ <p><code>.hide</code> is available, but it does not always affect screen readers and is <strong>deprecated</strong> as of v3.0.1. Use <code>.hidden</code> or <code>.sr-only</code> instead.</p>
+ <p>Furthermore, <code>.invisible</code> can be used to toggle only the visibility of an element, meaning its <code>display</code> is not modified and the element can still affect the flow of the document.</p>
