Why can't I change the width?

Question

The width of some elements in my code doesn't change. I wrote "width:0px;" and the element ids (with #) correctly. Why doesn't it work??
(Look at the bottom of CSS. The red points should limit the lines.)

Answer 1

You need to write width: 0 !important; because the other CSS rules will overwrite that one.

Answer 2

True, but the ! NOT operator is for scripting languages. CSS is styling, and putting just “important” would seem like the value of something, not a note to override other styles. !important just makes it look special, IMO.

Thanks!

Answer 4

But that's not logical. Normally !important means that it's not important.
