Layer underneath another layer: auto position?

[Daria]

I have two layers, top and bottom. I want botom one to appear underneath top one at all times, regardless of the size of the content of the top layer. So, if I have 10 lines of text in the top layer , bottom will be in one position, but if I add more text to the top layer, bottom will shift down automatically.
I don't remember how to set up the positioning for these...

Anyone?

Sounds like

<div>layer 1</div>
<div>layer 2</div>

to me.
