title: How do I vertically align a content div between a header and footer div?
body: <p>I have three rows of primary divs in my template.  I have a header, a content wrapper, and a footer.  The header butts right up against the top and the footer against the bottom.  I have a content wrapper div in between the two.  I basically want to center the content wrapper vertically within the two divs.  The content div will always be a dynamic height, so the line-height method won't work for me.  What would be the best method for me to use for this?</p>
