Browsers and layer support

[pas]

How's browser support with layers? How far back - about the version 3's of browsers? I'm thinking about switching from tables to layers. BTW, by layers I mean of this sort:

<div id="nameofLayer" style="position:absolute; width:200px; height:200px; z-index:1; left: 50px; top: 150px">This is our layer text.</div>

In general you could say CSS support started with version 4 browsers and is more reliable in version 6 browsers.

Do you really have to support version 3 browsers?
