ok you can have only one icon for all items like this...
add this in custom css file:
.sprocket-headlines-badge span:before {
font-family: FontAwesome;
content: "\f0a1";
font-size: 21px;
}
To create a custom CSS file, you just have to create a new css file at /templates/[TEMPLATE]/css/ and name it [TEMPLATE]-custom.css. The new custom CSS file will automatically get loaded by the Gantry 4 Framework.
NOTE: The use of [TEMPLATE] in this guide is intended as a placeholder for the name of the template's primary directory. Replace [TEMPLATE] with the template directory name in order for these instructions to work with your site.
