Add this to your
extra.less template:
CSS:
.userBanner.userBanner--staff:before
{
.m-faContent(@fa-var-shield);
margin-right: 3px;
}
Alternatively, you can use this:
CSS:
.userBanner.userBanner--staff .userBanner-before
{
.m-faContent(@fa-var-shield);
margin-right: 3px;
}
Either one should work just fine. Of course you'll want to change "shield" to whichever font awesome icon you'd like to use there.
