HTML CSS DIV边距顶部无效

Question

I'm trying to make a menu bar that is vertically on the right side of the screen. The menubar should touch the horizontal main navigation bar on the top, but i can't set the top margin of the vertical bar to zero.

Here: https://www.dropbox.com/s/azz5diwqzfchued/Schermafdruk%202015-09-08%2022.22.09.png?dl=0

is a screenshot of how chrome inspect element shows the problem, this might make things a bit clearer.

Thanks in advance!

Answer 1

According to the element inspector your margin-top style got a syntax problem. From the looks of it I'd say you used a double ':' (colon) character. Try removing the double ':' character and try again.

If this still doesn't work, maybe another style is overriding your new one so you could try:

margin-top: 0 !important;

This will make sure this style will always have the highest priority.
