title: How to get rid of the space between divs
body: <p>I have a thick white line on my webpage in between two divs and every time I delete my <code>&lt;ul&gt;</code> in the second div the white line goes away. How do I delete the white line and keep my <code>&lt;ul&gt;</code>? I have tried removing all of the CSS elements, without success. Even with an empty <code>&lt;ul&gt;</code> the space is there...</p>
