title: CSS Same Height As Other Div?
body: <p>I have a website I am developing.
  I have this div with another div inside of it named 'second'.
  I want the first div to be the same height as 'second'.
  So I make the <code>height:</code> of the first div: <code>height:auto;</code> but that doesnt work, that makes it shorter then 'second'. How do I set the height of the first div to match the 'second' div?
  The reason why the height needs to be  the same as 'second'is because 'second' has expanding content in it.</p>
