How do I remove the window title?

I welcome!

Can I remove the title from one specific window to the other he left?
For example, if I change this style -

.v-window-outerheader {
    background: url("window/img/top-right.png") no-repeat scroll right top transparent;
    height: 23px;
    margin-left: 9px;
    padding: 15px 40px 11px 12px;
}

…lost the title at all.
I would be grateful for your help!:smiley:
