Yes, I know this is probably a bad thing to want to do.
I have converted a web site to Drupal. I think I've done a reasonably good clean job with the markup and CSS starting with the Zen theme. All font sizes are set in em. It's a fixed width layout. That might be a bad decision but ... I basically copied the old site design.
The menu at is a nice horizontal ul inside a div. One of the users seems to be in the habit of increasing the text size by zooming with Firefox with "Zoom Text Only" checked or changing the text size in I.E. The problem is that the menu area is a fixed size so the right hand menu options drop off the end and disappear.
The old site seemed to have some magic or hack that avoided this. When zooming the text size, all text zooms except the menu. It stays the same. I've poked around with Firebug but haven't been able to find how they do it. The client would like the new site to behave the same way. That menu on the old site is a table so I wonder if tables are immune to the text resize.
Thanks for any suggestions.
