We could make an entire div tag clickable by redirecting the click to a page and by changing the cursor sytle to a pointer. This is good if you want your logo or your banner to be clickable, specially if the logo is embedded together with the banner. Making the entire banner clickable would be very beneficial to your site.
<div onclick="location.href='http://www.tildemark.com/';" style="cursor: pointer;">
</div>
