You can grab all the old stuff from an old .css file, like this from a default css file on my 3.8 site:
Code:
.tborder
{
background: #D1D1E1;
color: #000000;
border: 1px solid #0B198C;
}
.tcat
{
background: #869BBF url(../../images/gradients/gradient_tcat.gif) repeat-x top left;
color: #FFFFFF;
font: bold 10pt verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif;
}
.tcat a:link, .tcat_alink
{
color: #ffffff;
text-decoration: none;
}
.tcat a:visited, .tcat_avisited
{
color: #ffffff;
text-decoration: none;
}
.tcat a:hover, .tcat a:active, .tcat_ahover
{
color: #FFFF66;
text-decoration: underline;
}
etc
