Help with username design

Ok here

a[href="/u22"] {
background-image: url(http://forum.ragezone.com/images/backround16.gif);}

i add this but why it is not working?????

I Just check the users profile but it is correct /u22

So, the code should work. But, I don't know, maybe need to add an !important. Try this:

Code:

a[href="/u22"]{
background-image: url(http://forum.ragezone.com/images/backround16.gif) !important;
}

yeah whats the a[href="/u22"] ?
user id ?

I don't recall ever seeing that being used in css this way before,
So may be thats the problem?
