Modal elements in web pages -from now on overlays- are a great help to guide the visitors of the webs, since they allow blocking the content of a web except what we want.
Simple Overlay is a jQuery plugin that allows us to do just that, all quite ornate thanks to the use of various CSS3 techniques and of course animations made in jQuery, one of the great advantages of using a plugin from this library.
It is a simple to use plugin, and very useful for many websites. As always, minimal handling of jQuery and Javascript is necessary.
