margin leakage: potential misalignment caused by nested DIV elements

I am experiencing a strange issue where the margin of a nested DIV is "leaking" out of its parent container.

For a better understanding, check out this test case:

http://jsbin.com/ibaze

The outer wrapper (highlighted in red) does not align perfectly at the top unless there is a text node or overflow: auto; applied to that element. (Tested on Firefox and Safari.)

Although using overflow as a workaround helps, I am curious to understand why this behavior occurs in the first place. Any insights would be greatly appreciated!

 * This test case is minimal except for the script at the bottom, which only demonstrates the workarounds

Answer №1

Your issue is due to the collapsing of vertical margins in CSS, which is the expected behavior.

To resolve this, remove the margin from #inner and instead add a padding: 50px; to your #outer element for the desired outcome:

* {
    margin: 0;
    padding: 0;
}

body {
    color: white;
    background-color: blue;
}

#outer {
    padding: 50px;
    background-color: red;
}

#inner {
    background-color: green;
}
