Christmas Calendar (Codepen)

Goggwell · December 3, 2014

I was scavenging Codepen for something really Christmas-y, and I found it!

Check it out:

It's a Christmas Calendar that actually works in real-time! Amazing, huh?

Using animations, CSS and the latest in great HTML coding!

Too lazy to check out Codepen? View the coding down below:

The coding is in order from HTML --> CSS --> Javascript/jQuery

Don't forget to link the CSS and JS files in your HTML code! And add the DOCTYPE at the top of the HTML code as well!

Have fun!
