Example 2: Font Awesome
Font Awesome is a font and icon toolkit based on CSS and Less.
It was made by Dave Gandy for use with Bootstrap, and later was incorporated
into the BootstrapCDN.
Font Awesome has a 38% market share among those websites that use third-party
font scripts on their platform, ranking it second place after Google Fonts.
