Thanks for your reply. I think I was not clear enough.

1) For sure I am NOT recomending a big canvas for a regular web page!

2) I don't use table for layout. What I mean is: if you have to show a table (tabular data) construct it as image and you will be safe.

3) When I say "use only a big canvas" I mean COMPLEX applications like this drawing tool: https://www.bobsprite.com/editor
