[tech_learn]

Hi

this is code



<style type="text/css">
cursor:pointer;
margin-bottom: 0px;
background-image:url('Tricolor3A.gif');
color:black;
width:170;


padding:6px 2px 2px 2px;
text-align:center;
valign:middle;
font-weight:bold;
font-size:11px;
text-decoration: none;
/*/*/border-bottom:1px solid #ffffff;/* */
}
</style>

i want to change the height. eg. if Netscape i want to change height to 25px or if mozilla height to 27px etc.
