[support] A simple question from a beginner

I have included the Site Title and Slogan in a header background image that occupies the header of my site. Can someone please tell me how to code (and where to put it) a link so that a click anywhere in the header takes the user to the front page? I would have no problem with this if it were simple HTML, but the compartmentalized PhP structure of Drupal has me pretty confused. Thanks in advance, Steve Hays Classics Ohio University
