Show elem only if content of page is taller than viewport

Forcing a download of scripts for something so simple is worse than not having a top link at all, imho.

I guess so… loading a somewhat massive plugin for this seems a little like overkill… oh well, too bad… I really wanted to see if I could do this…

I really wish Javascript would detect changes in dimensions of elements when this changes dynamically… oh well… can’t have everything…;~))

thank you…
