Me too. I suspect what he meant was that you can come up with a simple layout with 10 minutes of reading, but that's a strawman. The real problem is that it's extremely easy to rapidly make a once-simple layout a nightmare to maintain or debug. With bitter experience I've realized I need to be extremely disciplined when I use the CSS directives margin, padding, and float. Everything else is relatively straightforward, with localized implications. But anytime you mess with the box model itself you really need to think about the big picture of your page's layout.
