I found a great article today over at Digital Web entitled “Web Design 101: Positioning.” I design and code (xhtml/css) websites for a living, so I know most of this, and thats why it’s called “101″, however this is one of those articles I would have loved to find a couple years back to explain the mystical world that is positioning.
It’s a tough, tough thing to grasp, especially at first, but is essential and will make a designer’s/developer’s life MUCH easier if floats weren’t the only option for everything. It did mine.
I think I can speak for the most of us when I say that once I learned and read up on positioning (and anything css for the most part), I basically just jumped right in because I learn better through trial and error, but I think if you can avoid that do it, or at least do both simultaneously, it would be a good idea to code while you are reading articles like this.
So even if you think you know everything there is about positioning, go read the article. I’m sure if nothing else, it’s a good refresher.
