Hi!
I cant solve this puzzle.In my code the maincontentpic div doesnt show.The image (CompHandWeb.jpg)is in the same folder and at the right place, it showed up before i altered the code. The second part after the gap is the Css which is also working, apart from said maincontentpic div. Whats wrong ? thx !
