Basic - How to add a span to the following css?

[herghost]

Hi all,

 

How would I add a span class called subh to the following css under the <ul>

 

Basically I just want a way of making some of the <ul> <li> in bold?

.bg {background: url(images/button4.gif);}
.menu {padding:0 0 0 32px; margin:0; list-style:none; height:40px; background:#fff url(images/button1a.gif) repeat-x; position:relative; font-family:arial, verdana, sans-serif; }
.menu li.top {display:block; float:left; position:relative;}
.menu li a.top_link {display:block; float:left; height:40px; line-height:33px; color:#bbb; text-decoration:none; font-size:11px; font-weight:bold; padding:0 0 0 12px; cursor:pointer;}
.menu li a.top_link span {float:left; font-weight:bold; display:block; padding:0 24px 0 12px; height:40px;}
.menu li a.top_link span.down {float:left; display:block; padding:0 24px 0 12px; height:40px; background:url(images/down.gif) no-repeat right top;}
.menu li a.top_link:hover {color:#000; background: button4.gif) no-repeat;}
.menu li a.top_link:hover span {background:url(images/button4.gif) no-repeat right top;}
.menu li a.top_link:hover span.down {background:url(images/button4a.gif) no-repeat right top;}

.menu li:hover > a.top_link {color:#000; background: url(images/button4.gif) no-repeat;}
.menu li:hover > a.top_link span {background:url(images/button4.gif) no-repeat right top;}
.menu li:hover > a.top_link span.down {background:url(images/button4a.gif) no-repeat right top;}

.menu table {border-collapse:collapse; width:0; height:0; position:absolute; top:0; left:0;}

.menu a:hover {visibility:visible;}
.menu li:hover {position:relative; z-index:200;}

.menu ul,

.menu :hover ul.sub li a.fly {background:#fff url(images/arrow.gif) 80px 7px no-repeat;}
.menu :hover ul.sub li a:hover {background:#999999; color:#fff;}
.menu :hover ul.sub li a.fly:hover {background:#999999 url(images/arrow_over.gif) 80px 7px no-repeat; color:#fff;}
.menu :hover ul li:hover > a.fly {background:#999999 url(images/arrow_over.gif) 80px 7px no-repeat; color:#fff;}
