2nd css sheet pushes content down

A margin appears above my webpage when a second style sheet is added.

Before:

<link rel="stylesheet" href="styles/style.css" type="text/css" charset="utf-8" />

After:

<link rel="stylesheet" href="styles/style.css" type="text/css"/>
<link rel="stylesheet" href="styles/image-slideshow.css" type="text/css" charset="utf-8" />

Any ideas how to fix this so no margin appears? :confused:

Does it look right to you?
