CSS Adjust Parent DIV size if Absolute Child DIV falls outside boundaries

问题

I have a parent div that is a specified width and height. If I have a child div inside that, that is outside the boundaries, is there a way to make the parent div adjust size to fit the child div?

EX:

<div style="width:500px; height:500px; position:relative;">
  <div style="width:300px; height:300px; position:absolute; top:250px;">
    Some Content
  </div>
</div>

As you can see in this example the child div would overflow the parent div on the bottom by 50px. I do not want to use overflow:auto because that just creates scrollbars. I really want the parent div to adjust and add 50px in height to compensate for the child div.

You want to push the child down 250px from the top of the parent so do no use top:250px. Use margin-top:250px; and position:relative;
