Sometimes text just isn't enough. Icons can communicate a lot of information to a user and how they can interact with the content on your site. The challenge often lies in creating, curating and maintaining icon images.
Similar to Bootstrap Font Awesome offers consistency by providing a font library of CSS-based scalable vector icons. And with over 600 icons in the library, there are plenty of ways to visually communicate information to users.
To use the icons from Font Awesome, simply link to the CSS library and start referencing icons.
Here is a brief example:
<i class="fa fa-exclamation"></i>
