Beside from the already included glyphicons from Bootstrap, this theme comes ready with some of the most famous icon bundles:
The premium icon font for the Ionic Framework.
Entypo pictograms by Daniel Bruce — www.entypo.com
A set of 100 high quality outline icons.
The iconic font and CSS toolkit.
All these icons can be placed in just about any other element, so long as they are a separate HTML element (e.g., a
<i>). See the examples below for how to put them to use.
