Add frames to postbit

[booble]

I have this postbit:



I' searching how add this frame to the other info.

firebug say the frame has: (but I don't find it on templates for remove)

.bppostbit {
background: url("images/.../gradients/back6.png") repeat-x scroll left top rgba(0, 0, 0, 0);
border: 1px solid #C4C4C4;
margin-top: 2px;
padding: 3px;

if I add this to .postbitlegacy dl.userinfo_extra dd, .postbitlegacy dl.userinfo_extra dd a without deleting .bppostbit:



Where is .bppostbit ??


EDIT: OK, I found this and fixed.
