You can place Font Awesome icons just about anywhere using the CSS Prefix fa and the icon's
name. Font Awesome is designed to be used with inline elements (we like the <i> tag for
brevity, but using a <span> is more semantically correct). 
<i class="fa fa-camera-retro"></i> fa-camera-retro
 
    -   If you change the font-size of the icon's container, the icon gets bigger. Same things goes for color,
    drop shadow, and anything else that gets inherited using CSS. 
 
 
 
 fa-lg
 fa-2x
 fa-3x
 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
 
    -   If your icons are getting chopped off on top and bottom, make sure you have
    sufficient line-height. 
 
 
 
    -    Home
-    Library 
-    Applications 
-    Settings 
 
 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>  Home</a>
  <a class="list-group-item" href="#"><i class="fa fa-book fa-fw"></i>  Library</a>
  <a class="list-group-item" href="#"><i class="fa fa-pencil fa-fw"></i>  Applications</a>
  <a class="list-group-item" href="#"><i class="fa fa-cog fa-fw"></i>  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>
 
 
 
  …tomorrow we will run faster, stretch out our arms farther… And then one fine morning—
So we beat on, boats against the current, borne back ceaselessly into the past. 
 
 Use fa-border and pull-right or pull-left for easy pull quotes or
article icons. 
<i class="fa fa-quote-left fa-3x pull-left fa-border"></i>
...tomorrow we will run faster, stretch out our arms farther...
And then one fine morning— So we beat on, boats against the
current, borne back ceaselessly into the past.
 
 
 
 Use the fa-spin class to get any icon to rotate. Works well with fa-spinner, fa-refresh, and fa-cog. 
<i class="fa fa-spinner fa-spin"></i>
<i class="fa fa-circle-o-notch fa-spin"></i>
<i class="fa fa-refresh fa-spin"></i>
<i class="fa fa-cog fa-spin"></i>
 
  CSS3 animations aren't supported in IE8 - IE9. 
 
 
   normal
  fa-rotate-90
  fa-rotate-180
  fa-rotate-270
  fa-flip-horizontal
  fa-flip-vertical 
 
 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
 
 
 
     fa-twitter on fa-square-o
    fa-flag on fa-circle
    fa-terminal on fa-square
    fa-ban on fa-camera 
 
 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>
fa-twitter on fa-square-o<br>
<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>
fa-flag on fa-circle<br>
<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>
</span>
fa-terminal on fa-square<br>
<span class="fa-stack fa-lg">
  <i class="fa fa-camera fa-stack-1x"></i>
  <i class="fa fa-ban fa-stack-2x text-danger"></i>
</span>
fa-ban on fa-camera
