fa-4x

fa-5x

To increase icon sizes relative to their container, use the fa-lg (33% increase), fa-2x, fa-3x, fa-4x, or fa-5x classes.

<i class="fa fa-camera-retro fa-lg"></i> fa-lg
<i class="fa fa-camera-retro fa-2x"></i> fa-2x
<i class="fa fa-camera-retro fa-3x"></i> fa-3x
<i class="fa fa-camera-retro fa-4x"></i> fa-4x
<i class="fa fa-camera-retro fa-5x"></i> fa-5x

Use fa-fw to set icons at a fixed width. Great to use when different icon widths throw off alignment. Especially useful in things like nav lists & list groups.

<div class="list-group">
<a class="list-group-item" href="#">
<i class="fa fa-home fa-fw"></i>&nbsp; Home
</a>
<a class="list-group-item" href="#">
<i class="fa fa-book fa-fw"></i>&nbsp; Library
</a>
<a class="list-group-item" href="#">
<i class="fa fa-pencil fa-fw"></i>&nbsp; Applications
</a>
<a class="list-group-item" href="#">
<i class="fa fa-cog fa-fw"></i>&nbsp; Settings
</a>
</div>

• List icons
• can be used

Use fa-ul and fa-li to easily replace default bullets in unordered lists.

<ul class="fa-ul">
<li><i class="fa-li fa fa-check-square"></i>List icons</li>
<li><i class="fa-li fa fa-check-square"></i>can be used</li>
<li><i class="fa-li fa fa-spinner fa-spin"></i>as bullets</li>
<li><i class="fa-li fa fa-square"></i>in lists</li>
</ul>
