Why does this CSS margin-top style not work?

Question

I try to add margin values on a div inside another div. All works fine except the top value, it seems to be ignored. But why?

What I expected:
<

Answer 1

Use padding-top:50pxfor outer div. Something like this:

#outer {
    width:500px; 
    height:200px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:table;}

Note: padding will increase the size of your div. In this case if the size of your div is important, I mean if it must have a specific height. decrease the height by 50px.:

#outer {
    width:500px; 
    height:150px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:table;}
