Footer jumping if mouseing over a link

I am experiencing an oddity that I cant figure out.

I have a page with an almost default install of modx9.6.3 and the default template, and when viewed with IE6, if you mouse over links in the body (not the main menu) the footer will jump/expand by an inch or two.

For the life of me, I cant figure out why

Any ideas??

Hi there,

difficult to say, but i’m guessing it has something to do with your shadowbox-script, maybe get rid of the shadowbox-js just to see if that happens with any other link ...

also try to validate your website, you get about 20 errors for the html, and about 12 for css:
