Use overlay for entire page, not just the window width and height.

[GoogleCodeExporter]

The issue was that people could scroll down and then access certain parts of 
the site. That's not good. 

So I modified the code to use the overlay for the entire page width and height. 

Change out: 

  document.documentElement.clientHeight

with

  document.body.clientWidth

And then for a simple way to get the warning window to stay in the visible 
frame, replace:

  _dd.style.top = ((_height-_ddh)/2)+"px"

with

  _dd.style.top = "50px"

Produces a much better result. You could also rejig it so that it positions the 
box to the middile of the visible screen but covers the entire body with the 
overlay. 

JP Out.

i implemented this and it looks awesome. but for some reason the overlay covers 
my entire page, except about 40 pixels at the way bottom. any suggestions as to 
why this might be happening?

That's because the original solution has got a typo - it references "width" 
instead of "height". To correct:-

Replace;

    document.documentElement.clientHeight

with

    document.body.clientHeight

And then to retain the overlay centered on the visible viewport, replace;

    _dd.style.top = ((_height-_ddh)/2)+"px"

with
    _dd.style.top = ((document.documentElement.clientHeight-_ddh)/2)+"px"

You bet. 

Would you consider officially moving this over to Github and possibly merging 
the changes that these guys made: 

https://github.com/jbueza/IE6-Warning-with-Localizations
https://github.com/rtgibbons/ie-upgrade-warning
https://github.com/monobasic/ie-upgrade-warning

I would love to develop this a bit further as well and much prefer 
collaborating on GitHub.

Cheers,

Josh
