I have a layer in the webpage lets say left 200 top 300. The width and height follows the client window.

Now I want to place a Editor inside this, but I want it to resize so it always fills the layer area.

 

For width this is no problem as I set width of editor = 100%. Is there a way I can do the same for the height?

Or alternativly I could use a javascript to control the height when user resizes the client window, but

what ID prefix/suffix could I use to acheive this?
