Height and width

Question

I've taken two quizzes recently with similar questions along the lines of "is width=50% the same as width=50" and in html5 I know you can input the width value as just "50" but in other cases you can not. What are the exceptions to this rule?

Answer 1

50 (or 50px) and 50% is not the same. The % depends on the width of the window/screen.
