you need to put all the CSS in style2.css

body{
  font-family:Verdana, Arial, Helvetica, sans-serif;
  font-size: 10px;
  padding: 0px;
  margin: 0px;
}
td {
  font-family:Verdana, Arial, Helvetica, sans-serif;
  font-size: 10px;
}
#mySideNav {
  border-right: 1px solid #000000;
}
#myTopNav {
  border-bottom:1px solid #000000;
}
a.side{
  text-decoration: none;
}

a.side:visited,a.side:link,a.side:active {
   color: black;
}

a.label{
  color:#0000FF;
  text-decoration: none;
}

also, you should really look into asp includes if you are having to type the header in every page.
