As you can see, all the elements are kept on separate lines so the user can easily navigate the calendar. Sadly, the developer didnโt give us a fully functional calendar, but we can work on it to make it complete. You can take this outline and use your own animation effects and features to make the calendar interactive.
Simple Calendar
Simple Calendar is almost a fully functional calendar template. You can easily navigate through the months, plus you can also add events to this calendar. The creator has given different colors for the predefined groups, like birthdays, festivals, and important events. Unfortunately, you donโt get the option to set your own custom colors for your event. But you can edit the code and add your own custom features. The overall design of this example is practical and can be applied easily to any website/application. Since this calendar has different functionality, the code is a bit complex. After a few minutes, you can understand the code structure and start playing with it on the CodePen editor.
Round Calendar
As the name implies, this calendar uses a circular design concept. The circles are used only to highlight the selected dates, so you get a normal clean-looking calendar in this case.

Dice Calendar
Dice Calendar is another interesting CSS calendar design, like the circular calendar mentioned above. The creator has used a rolling dice concept for this calendar, as the name implies.

By making a few design adjustments, you can make this calendar a perfect fit for all modern websites and applications.

Hence, you can edit and visualize the results before using it on your website or application.
