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

try this:

#outer {
    width:500px; 
    height:200px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:table;
}
#inner {
    background:#FFCC33;
    margin:50px 50px 50px 50px;
    padding:10px;
    display:block;
}​

Good luck

Answer 2

I guess setting the position property of the #inner div to relative may also help achieve the effect. But anyways I tried the original code pasted in the Question on IE9 and latest Google Chrome and they already give the desirable effect without any modifications.

Answer 3

Just for a quick fix, try wrapping your child elements into a div element like this -

<div id="outer">
   <div class="divadjust" style="padding-top: 1px">
      <div id="inner">
         Hello world!
      </div>
   </div>
</div>

Margin of inner div won't collapse due to the padding of 1px in-between outer and inner div. So logically you will have 1px extra space along with existing margin of inner div.

Answer 4

Not exactly sure why, but changing the inner CSS to

display:inline-block;

seems to work;

Answer 5

Have you tried !important before all, it will force everything:

margin:50px 50px 50px 50px !important;

Answer 6

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;}
