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

<p><i class=" fa-lemon-o hidden-print t1 icon-large"></i> fa-lemon-o hidden-print t1</p>
<p><i class=" fa-lemon-o hidden-print t1 icon-2x"></i> fa-lemon-o hidden-print t1</p>
<p><i class=" fa-lemon-o hidden-print t1 icon-3x"></i> fa-lemon-o hidden-print t1</p>
<p><i class=" fa-lemon-o hidden-print t1 icon-4x"></i> fa-lemon-o hidden-print t1</p>
If your icons are getting chopped off on top and bottom, make sure you have sufficient line-height.
  • Font Awesome icon can be used
  • to easily replace lists

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

<ul class="icon-ul">
  <li><i class="icon-li  fa-lemon-o hidden-print t1"></i>Font Awesome icon can be used</li>
  <li><i class="icon-li  fa-lemon-o hidden-print t1 icon-spin"></i>to easily replace lists</li>
</ul>

<i class=" fa-lemon-o hidden-print t1 icon-2x pull-left icon-border"></i>
Use a few styles together and you'll have easy pull quotes or a great introductory article icon.

  normal
  icon-rotate-90

<i class=" fa-lemon-o hidden-print t1"></i>  normal<br>
<i class=" fa-lemon-o hidden-print t1 icon-rotate-90"></i>  icon-rotate-90<br>

<i class=" fa-lemon-o hidden-print t1 icon-flip-horizontal"></i>  icon-flip-horizontal<br>
<i class=" fa-lemon-o hidden-print t1 icon-flip-vertical"></i>  icon-flip-vertical

<i class=" fa-lemon-o hidden-print t1 icon-2x icon-spin"></i>
<i class=" fa-lemon-o hidden-print t1 icon-3x icon-spin"></i>
<i class=" fa-lemon-o hidden-print t1 icon-4x icon-spin"></i>

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