<h3>{{_i}}How to customize{{/i}}</h3>
<p>{{_i}}Modifying the grid means changing the three <code>@grid*</code> variables and recompiling Bootstrap.

<div class="span5">
<p>{{_i}}Bootstrap doesn't automatically include these media queries, but understanding and adding them is very easy and requires minimal setup. You have a few options for including the responsive features of Bootstrap:{{/i}}</p>
<ol>
<li>{{_i}}Use the compiled responsive version, bootstrap-responsive.css{{/i}}</li>
<li>{{_i}}Add @import "responsive.less" and recompile Bootstrap{{/i}}</li>
<li>{{_i}}Modify and recompile responsive.less as a separate file{{/i}}</li>
</ol>
<p>{{_i}}<strong>Why not just include it?</strong> Truth be told, not everything needs to be responsive. Instead of encouraging developers to remove this feature, we figure it best to enable it.{{/i}}</p>
