We want to incorporate modal window pop ups that are 100% Javascript based in our Web site design. I have checked many different options for modal window, but cannot decide which one is the best option.

Which modal window pop up option that is 100% Javascript do you suggest as the best choice and why?

And when replying kindly provide a link to the modal window that you are suggesting. I mean a link to the page which would have a demo of it as well as the download code.

Thank you.
