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:
<div class="blockTitle"><{$block.title}></div>
<div class="blockContent"><{$block.content}></div>
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.
