Sideboxes keep adjusting position based on viewing page length

I have some sideboxes on the left that keep repositioning themselves. Based on my testing, it seems the position changes when the page that is being viewed has different lengths. I searched the forum, but perhaps I am stating the problem more concisely here.

Sorry, not seeing the problem.

click on a page like advanced search where the length of the page is longer...

You have eliminated nearly all styling for your site, so the stock alignment is gone, letting the sideboxes revert to default HTML "centered" vertical alignment. /* This positions the sideboxes */ #navColumnOneWrapper{...} /* ?don't know if right? */ Try ```
#navColumnOne {vertical-align: top;}

Thank you, problem solved.

Just a suggestion; eliminating all of the standard Zen Cart stylesheet as you did means that a vast number of situations that have been accounted for in generally useful ways will be unset for you, and you will waste a lot of time finding ways to make them work normally, or else have odd bits of appearance in miscellaneous places. By all means prune the stylesheet of rules that are not helpful for you, but you would find life a lot easier if you used the template_default stylesheet as a base for your custom stylesheet... and you would not have to bother us to help restore the styles you deleted.
