How to get a box to appear from the top of the browser window on page load?
<p>I want a box to appear from the top of the browser window upon page load.</p>

<p>Ideally it would look like this:</p>

<p><a href="http://demo.cookieconsent.silktide.com/" rel="nofollow">http://demo.cookieconsent.silktide.com/</a></p>

<p>So the page loads and this slides down. </p>

<p>How would I achieve this?</p>

<p>I have looked at <a href="http://jqueryui.com/demos/dialog/" rel="nofollow">http://jqueryui.com/demos/dialog/</a> but it doesn't do the above it seems.</p>
