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
• as bullets
• in lists

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>

To arbitrarily rotate and flip icons, use the fa-rotate-* and fa-flip-* classes.

<i class="fa fa-shield"></i> normal<br>
<i class="fa fa-shield fa-rotate-90"></i> fa-rotate-90<br>
<i class="fa fa-shield fa-rotate-180"></i> fa-rotate-180<br>
<i class="fa fa-shield fa-rotate-270"></i> fa-rotate-270<br>
<i class="fa fa-shield fa-flip-horizontal"></i> fa-flip-horizontal<br>
<i class="fa fa-shield fa-flip-vertical"></i> icon-flip-vertical

To stack multiple icons, use the fa-stack class on the parent, the fa-stack-1x for the regularly sized icon, and fa-stack-2x for the larger icon. fa-inverse can be used as an alternative icon color. You can even throw larger icon classes on the parent to get further control of sizing.

<span class="fa-stack fa-lg">
  <i class="fa fa-square-o fa-stack-2x"></i>
  <i class="fa fa-twitter fa-stack-1x"></i>
</span>
<p>fa-twitter on fa-square-o</p>
<span class="fa-stack fa-lg">
  <i class="fa fa-circle fa-stack-2x"></i>
  <i class="fa fa-flag fa-stack-1x fa-inverse"></i>
</span>
<p>fa-flag on fa-circle</p>
<span class="fa-stack fa-lg">
  <i class="fa fa-square fa-stack-2x"></i>
  <i class="fa fa-terminal fa-stack-1x fa-inverse"></i>
