I think Massy, like me, uses text based browsers only. But I'm sure, it shouldn't be too difficult to find the javascript in question. Still, for Massy himself the image would be without use as well. :-)

Ah, well if you do want to fix it Massy then what the picture shows is that div#middle aligns its left edge to the center of div#middle_outer on Firefox 12 (with or without javascript enabled) rather than being in the middle of it (it works on Chromium no problem).

I will read the article once I am done struggling with the alignement of divs on my own project.
