I recently created a pure CSS/HTML functional calendar which can correctly display months from Jan 1800 to Dec 2999 with no JavaScript, all through the use of CSS variables and some clever comparison logic functions I created, also in CSS.

nothing. html and css alone are almost useless without javascript

1. A feature-rich admin template, with advanced features like modals, tooltips, form validation, counters, classes for feature detection, popups, sliding menu, etc

2. My website

Thank you. 😊

All the following pens are like 3-4 years old. These may/may not be cool but the title says "coolest things you've made"! 😁

1. A Rainbow Loader
2. Reflection effect
3. A hole (parallax?)
4. A Dribbble clone that I'm proud of

My whole homepage, stibelman.com is pure HTML and CSS. I have some JavaScript for cleanup and automation of a couple of things, but the rest is CSS.
It's kind of a hobby of mine to try to solve JavaScript solutions in CSS.

I have a couple CSS illustrations:

1. NES controller
2. Death-Star illustration

I also created a Markdown -> HTML converter however it mainly uses JS.
