Modal windows are user interface elements. They sit on top of the main interface, so they do not interfere with underlying workflows.
These modal windows or boxes find many applications in in-app messaging. Some examples are welcome messages, product information, announcements, and so on.
CSS3, on the other hand, is much easier to work with. Yet examples of CSS modal windows are much harder to find.
This article presents a list of the best CSS modal windows for presentation.
The first CSS modal box example is the product of coder Niels Voogt. He embedded his modal into a details element.
The modal window opens when clicking on the details. Users close the window by clicking the cross or outside of the modal window.
This is possible because the overlay nests inside the summary element.
A great advantage is that older browsers like Internet Explorer 9 and higher also support it. A great way to interact with users.
