Using Font Awesome icons as CSS content

Standard

Font Awesome is a great web font icon pack to use with the Bootstrap 3 framework. While the implementation suggests using the <i> element; this is not always beneficial.

The solution is to specify the icons using pure CSS. This can be accomplished by substituting content values for the relevant icon within the Font Awesome font-family.

Take this CSS class for example which uses the “check” icon.

Now using the <a> tag you can add a check icon to a Bootstrap 3 button
