How do I make the opt-in box fade in and float on top of the site?

I need to make my Constant Contact Opt-in box fade in after they open the main website page. So they will have to either signup or hit the close button to then get to the website.
How do I do that and have the signups go into a specific email list?

This type of web programming varies based on your website and unfortunately is beyond the scope of this forum. The actual sign up to specific lists can be found here.
