Floating a DIV to right of <Hx> element?

[Philip Semanchuk]

Hi all,
I'm trying to find a way to place a small DIV just to the right of a
header element. I've found a solution, but it is crude and I was hoping
for something more elegant. I'd appreciate any suggestions you might have.

My H1 elements have width=75%, and to the right of each I want a small
DIV that contains a hyperlink to related content. I want that link to be
about 3em from the right-hand end of the header element. The only way I
can find to place it there is to float a DIV (which I call
LinkContainer) with width=25% (25% = 100% - the width of the header
element) to the right of the header, and place the hyperlink-containing
DIV in there. Here's an example:

What I find inelegant about my code is that if I change the header
width, I have to remember to change the LinkContainer width too. Also,
the width of my header elements shrinks corresponding to their
significance (h2 width=60%, etc.) so I need to define corresponding
LinkContainer DIVs for each header element. It seems like there ought to
be a way to avoid the LinkContainer DIV entirely, but I can't figure out
how to describe it to the browser.

Thanks for any help
Philip
