I'm customizing the Desktop Chaos theme. The original theme used html text for the blog title, bit I wanted to use a logo. There was no header graphic (header is built into a large background image - that goes behind content area AND header)
I added an invisible gif to the section of the stylesheet css and then added the following code (taken from a site that has clickable header) to make that area clickable...
<div id="blog-title .title" onclick="location.href='http://thejordanpease.com/test/';" style="cursor: pointer;">
but it made the WHOLE PAGE clickable, not just the "blog-title .title" area. Although other buttons work fine, clicking in the search box sets it off - which disables search.
