How is possible for me to have a html popup. I don't need a new window or tab, but like some sites have a like a popup window in front of the current page, disabling all content under it. I have seen this a lot for surveys.
I need to do a similar popup, and I am guessing/hoping that the "popup" can actually be a hidden div that I can unhide in the middle of the screen and disable all content behind it until the user clicks something from that div.
if someone can get me started, and maybe provide me with a sample script, that would be great.
