This is all the CSS that's present in that file:
body
{
padding: 1px 3px 0 3px;
}
span.prevnext a:link {font-size:500%}
span.prevnext a:visited {font-size:500%}
span.prevnext a:hover {font-size:500%}
span.prevnext a:active {font-size:500%}
#smfheader

.maintab_active_back
{
background: inherit;
background-color:#7392B0;
}
.maintab_active_last
{
background: inherit;
background-color:#7392B0;
}
#toppages{display:none}
.newtxt:after{content:"[new]"}
.newtxt{color:#000099;font-weight:bold;font-size:larger}
.newimg{display:none}
Chances are it is working and the changes are simply very minimal (glancing over it, seems like mostly minor font size, color and spacing changes to certain elements).
