This sort of thing hasn't been a problem for me at the TR site for quite a while. I used to have problems with the TR home page. The columns would overlap horizontally and vertically. I made a few complaints via the FAQ -> Contact Us feedback form. Over time the problems seemed to clear up.
I mentionedi in my feedback that I used enlarged fonts with the minimum font size set to 20 so that I don't have to position my nose three inches from the monitor surface to read web pages. I used, and continue to use, Mozilla.
The TR home page hasn't caused any problems for me for several months but once in a while I have the same sort of problem with a particular page. While I'm not an HTML guy I have suspected something like what apotheon suggested.
The worst page with this problem for me is the novell.com home page. My enlarged font setting doesn't fit into the various boxes defined on the page. This leads to me only seeing the tops of the letters for the various labels for drop down menus. I've complained to Novell but they haven't changed their page formatting to allow for scaleable page components.
My point is that there are some sites, but not many, where this sort of thing is a problem. I expect it has to do with some 18 year old propeller head web author who either doesn't know or doesn't care about making web pages accessible to people who don't use the default display settings in their browser.
I have to give TR credit for apparently fixing this problem in their home page. It would be funny if it turned out that TR actually hadn't done anything and my web browser just somehow managed to start displaying the TR pages properly. I really don't know.
