 <p>In your "mytngstyle.css" file, try changing the padding-top setting of "#nav li ul" to 0px instead of 1px. It seems like you are getting a 1 pixel space between your main menu item and the sub-menu <code>&lt;ul&gt;</code>. </p> <p>If the padding doesn't fix it look closely at some of the other settings to see why your getting that 1px space between the two <code>&lt;ul&gt;</code>'s.</p>
