title: Vertically aligning an image in a div element?
body: <p>I have a div element whose height I set with <code>em</code>, and whose width I set as a percentage. There is an image contained within. It has a width as a percentage (83%). However, if I am at a resolution where that div element is starting to get a little narrow, the image narrows up as well, but rather than taking up the entire div (as it should), the image just becomes small and appears just at the top of the div. To compensate for this, I want to vertically align my image within the div element. How can I do this?</p>
