Topic: How to change icon of post notify?

I want to replace default icons with new ones, but dont know how.
Old Icons are here:

.brd .main-content .main-item .icon {
     border-style: solid;
     border-width: 0.5833em;
     height: 0;
     width: 0;
     float: left;
     margin-top: 0.667em;
     margin-left: -2.417em;
     }

.brd .main-content .main-item .hn .posted-mark {
     position: absolute;
     font-size: 2em;
     width: 1em;
     left: -0.5em;
     top: 0;
     }

Tried with background: url(''), but It did not work for me.
