I split the SASS file, so the developer can decide which fonts and styles he really needs.

Installable via Bower:

bower install bitter-fontface 

Simply link into your HTML:

<linkrel="stylesheet" href="bower_components/bitter-fontface/bitter.css">

And start using it:

body{font-family: Bitter, serif}

Bold and italic:

strong{font-family: Bitter, serif; font-weight: bold; font-style: italic}
