Wow. It's an ancient site. I think that it was built standardly in its day, but it's been given a lot of adaption by various webmasters over the years. 18 errors on this page! And I don't know code well enough to rectify. I can see that every effort was made in the validator to be clear and simple, but it still is a little beyond me. Do you have an idea what I could study to make this more understandable to me and to be able to do something effective.
(note: according to the validator, a few of the errors seem to be within the juicebox script itself, but I could be reading that wrong.)
I did take the percentage information and changed it to pixels, but that was not enough to resolve the issue.
