The HTML hour
I’ve been trying for long to understand why those hellish cells in my HTML tables never keep the size I order them to have, and why dragging them is SO unsuccessful. I’ve seen a lot of bla-bla about transparent 1×1 pixel gifs, but never quite get it — people talk about it as if everybody know what they mean.
Eventually, I’ve found this page, which explains the whole stuff perfectly. I turns out to be very simple. A must-read if you want your pages to look a bit serious.
