This should work, substituting "tab_1" whatever ID you use (so make 3 copies of this, one for each button ID):
#forum_tabs > .forum_tab_links > span#tab_1 {
background-color: #003454;
background-image: -webkit-gradient(linear, left top, left bottom, from(#026cb0), to(#03568a)); /* Saf4+, Chrome */
background-image: -webkit-linear-gradient(top, #026cb0, #03568a); /* Chrome 10+, Saf5.1+ */
background-image: -moz-linear-gradient(top, #026cb0, #03568a); /* FF3.6+ */
background-image: -ms-linear-gradient(top, #026cb0, #03568a); /* IE10 */
background-image: -o-linear-gradient(top, #026cb0, #03568a); /* Opera 11.10+ */
background-image: linear-gradient(top, #026cb0, #03568a); /* W3C */
display:inline-block;
border-radius:3px;
border:1px solid #003454;
}
