You're getting your modules and blocks confused, which is confusing things. If I understand you correctly, you want to place the block title text over the block title graphic?
If so, you seem to be doing everything right, CSS-wise. You need to change the actual theme.html (or theme_blockleft/right.html, or whatever your theme uses. Most themes have something like this:
Quote:
<{$block.title}>
<{$block.content}>
Make sure your theme has this included, or something similar.
You also have to make sure the div class in your CSS matches the div class in your HTML file.
