This is where he's most wrong. Suppose he leaves out a close tag, or
puts one too many. The browser he's testing on politely produces some
sort of document tree without telling him there's anything wrong. It
guesses his intentions using crude heuristics and may be wrong. He
thinks he's looking at one document tree, in fact he is looking at
another. The rendering doesn't look quite how he intended it to, so he
starts fiddling with the styles to get it right. He infers from what he
sees a mistaken understanding of the box model that follows him around.
Errors and confusion multiply and propagate.
Catching as many errors as you can as early as you can is the only way
to do anything on a computer. Anyone will tell you that.
