You know, you're so fortunate that this dA bug hasn't so far affected your CSS layouts!
I've had to re-vamp mine and external url's are dodgey, so no graphics. No rightbox and contents... Sometimes things work and sometimes not. It's very disheartening. Had to remove my links because they weren't showing up as links, but lines of html! Hopeless.
It's such a shame if others, reading your tutorials get the same problems if they try anything in their journals too. I don't know what's going on here!
Meanwhile, well done for completing your tut!! I'll read it up later.
