popup window

Is it possible in html to show dialog box or popup window? I would like to put this code in <noscript> tags, so that when javascript is not enabled, the page will popup window with message that javascript is disabled.

You can create a "hidden" div element by zeroing out its height and width then activate it using the psuedo class hover.

Thanks. So, no direct/simple way of doing this.

That is the simple direct way to do it...lol No javascript required.
