Split IE window into two independent layers

[Zhiguo]

Hi, my friends,

In a standalone .js application, I have created an IE window.
Now I want to split the IE window into two independent layers:
(1) These two layers are both the same size as the IE window and
completely overlap with each other.
(2) The top layer is half transparent, and the bottom layer can be
seen.
(3) User can operate on the top layer, and the top layer controls the
bottom layer.
(4) The bottom layer may load web pages, while the top layer shouldn't
be influenced.

Is it possible to do that? And how?

Thanks in advance! Any help will be greatly appreciated!

Why are you focusing on IE when 50%-70% of Web surfers now use browsers
that are not IE?
