In the last couple of months I’ve worked on several projects that needed an overlay with some content on it. Some front-end frameworks as for example Bootstrap refer to them as modals.
You can find a lot of implementations that do exactly what I search for but they all have one major drawback: They rely on JavaScript.

Yes, sure, everyone has JavaScript enabled these days but why use a technique that you don’t necessarily need for a given problem? Also most implementations have drawbacks when it comes to mobile devices and responsive web design in general or accessibility. Apart from that they add a lot of code, that is not necessary for a lot of pages. Others might add dependencies such as for example jQuery which you don’t need at all on your micro-site.

To tackle these problems I decided to write my own implementation of a modal that fulfills what I need.

Modals built out of pure CSS

CSS Modal is the result of this experiment.

Here is what is cool about it:

• CSS Modal is built out of pure CSS while JavaScript is only for some sugar.
• The modals are designed using responsive web design methods.
• It is accessible, cross-browser, media-adaptive, small and fast!

Another cool thing is that you can use CSS Modal as Sass plugin and apply it to your custom classes using Sass placeholders.
