CSS Calendar Examples From CodePen

From a UI perspective, digital calendars are not the easiest to design. Considering they offer much more features compared to a printable calendar, their interfaces are much more complex. And looking at them from front-end point of view they’re definitely not a walk in the park to implement. Granted, new web layout modules like flex box and CSS grid have made things simpler, but getting some calendar UIs to work across different browsers can still be quite challenging.

With this in mind, I put together this list of some of the best CSS calendar examples I found on CodePen. Enjoy!
