FontAwesome CSS content value

gistfile1.txt

 Font Awesome - is a web font containing all the icons from the Twitter Bootstrap framework, and now many more. Whilst the implementation in Bootstrap is designed to be used with the <i> element (Bootstrap v2), you may find yourself wanting to use these icons on other elements.

 To do so, you'll need to use the following CSS on the desired element, and then substitute in the content value for the relevant icon.

 ********************************************

.element {
  position: relative;
}
 
/*replace the content value with the
corresponding value from the list below*/

.element:before {
  content: "\f000";
  font-family: FontAwesome;
  font-style: normal;
  font-weight: normal;
  text-decoration: inherit;
  /*--adjust as necessary--*/
  color: #000;
  font-size: 18px;
  padding-right: 0.5em;
  position: absolute;
  top: 10px;
  left: 0;
}

***********************************************

Note: it is not possible to use ':before' or ':after' pseudo content on <input> elements, however if you instead use <button> it will work as desired.
