Can somebody please tell me what is wrong with that? This arrogant program keeps saying "Oops, try again. Set the height of the

to 500px" .


the program/browser will read this incorrectly because you're missing a colon after height

height 500px;
height: 500px;

I can agree, it is arrogant, it should be giving you a correct error, however it's not a real error code, it's being read through the websites fault check.
