I'm having a hard time with my skeleton working with me. I want my site to be viewable in all browsers but at this time it's not. The links on the right hand side of my page www.gosalmonfishing.com is the problem. Any suggestions? Here is the "meat" of my style so far;

#header {
margin-left:15%;
width:800px;
text-align:center;
background:transparent;
font:bolder small-caps 22px Verdana, Arial, Sans-serif;
}

#date
{
text-align:center;

font-size: 12px;
font-weight: normal;
font-variant: normal;
}
#hlight {

}
#mainbody {

}
