I've a link as shown in image bellow
What I want is to do, is apply
background: url("img/icons.png") no-repeat -9px -91px;
Regarding your last comment you can do the following:
position:relative on the link's parent div and
position:absolute on the link's pseudo-element to make it independent from the
a and its declared
overflow:hidden. Adjust the position accordingly and everything should be fine.
