A:
It's a fixed positioned element.
#foo { position: fixed; top: 0; left: 0; width: 100%; z-index: 2; }
<div id="foo">
<p>This is my fixed element!</p>
</div>
Then you can use cookies to see if the user has visited before and show it with jQuery.
NOTE: The z-index on #foo must be higher than any elements that appear to be sitting on top of it.

Make sure you add a VALID DOCTYPE or IE7/8 will not support position: fixed.
