I am having this weird issue with IE8 and Opera where the Individual Client Engagement Form PDF download link on this page is changing font size on hover
Yep it seems it was the wrong doctype that was causing the problem, thanks for the mention of the validator, I wouldnt have even bothered to look at the doctype otherwise.
I think you’ve got some errors in your html that are causing problems. It looks like the UL and link are nested inside the h4. Run your page through the validator to fix up those errors, and then see if that fixes things.
BTW, there’s no real point using a UL for a single link. It takes at least 2 items to make a list.
