<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>Set <code>background-color: #fff;</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>
</div>
<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>
+
+ <div class="bs-callout bs-callout-info">
+ <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>
+ </div>
+
<h3 id="grid-media-queries">Media queries</h3>
- <p>We use the following media queries to create the key breakpoints in our grid system.</p>
+ <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, up to 480px) */
+/* 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-tablet) { ... }
+@media (min-width: @screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
-@media (min-width: @screen-desktop) { ... }
+@media (min-width: @screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
-@media (min-width: @screen-large-desktop) { ... }
+@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>

</div>
+ <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 <code>.col-md-*</code> grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices.</p>
+ <p>Using a single set of <code>.col-md-*</code> grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns in any <code>.row</code>.</p>

<p>Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding <code>.col-xs-*</code> <code>.col-md-*</code> to your columns. See the example below for a better idea of how it all works.</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>
