Pure CSS3 Modal Example

Modals are basically dialog's that pop out when a user clicks a link, image, button etc. This example will show you how you can do it with pure CSS3, no JavaScript needed. The modal contains a title, content, and close button so users can close the dialog, as well as a background that will also close the dialog when clicked.
