Here is code for a floating dive tag HTML: <div id="Layer1" style="position:absolute; left:239px; top:113px; width:459px; height:324px; z-index:1"> <div id="Layer2" style="position:absolute; left:148px; top:84px; width:232px; height:129px; z-index:2"></div> </div> If you move the first one the second div will move in relation to the first.
<div><div></div></div> is a DIV inside a DIV... so I don't know what you're asking. However, a div code inside of a div code is incorrect html, you should use a span within a div code. like <div><span></span></div> or even <div><span><span></span></span></div> of course put in the appropriate css attributes you wish to.
Whats the point in your post? It wasn't a total stupid question. Don't post if all you do is spam. I got my answer.
