Flash Document with dynamic geometry!

[preist]

Here's my question!

check this website: http://landing.ancestry.com/military/vday/
When I resize the window, so does the flash document, it changes it's geometry to fit my window not just shrinking or expanding the whole document, but managing it.

Lots of code might be involved, so what I'm looking for is a tutorial that teaches you how to make it.

Apprecicate, thank you.

When you say resize the window do you mean, change the resolution?

No, I mean it literary, resize the browser window.. something like:

var stageResizer:Object = new Object();
stageResizer.onResize = repositionContent;
function repositionContent(){
// Here you write the code to repositionate your elements.
// Something like this. :)
};
Stage.addListener(stageResizer);

But I need something more detailed, something better.

ssuming the foregoing is correct, here is a script that will center the content of a Web pabe both horizontally and vertically between a header and footer, as long as the content is smaller than the window height.

If the content, including header and footer, exceeds the window height, the footer will float to the bottom of the content.

If the window width is smaller than content width, the content will remain at a fixed width.
