I'm going to archive the current blog I'm using and want to point readers to a new blog by having them clicking on the banner image. Here's the stylesheet code now

#banner {
font-family: Verdana, Arial, sans-serif;
color: #000000;
background: #4573b3 url("http://www.blueskyresumes.com/img/bloglogo.gif")

How do I change this to make this banner a link to another site i.e. www.mynewsite.com
