Layout region

I'd shared recently about a text box shifting on the pages of my site. I was 
given a "really shouldn't use fixed layout. Doesn't work." advice.

Searched "fixed" and found that Nancy, Chuck, Anton, et al were all in

agreement in other posts.

Here's my site: www.deansdesigns.com.

If I truly want it to look like this, how would I do it otherwise? I've been 
using this fixed selection within a layout region. Anton said that there's 
many other ways to "skin this cat." I've just happened upon this one;
seemed 
to make sense. But it looks like I'm just making a mess out of the
"cat."
