I started a personal web dev challenge for myself to prevent my skills from getting rusty. You can follow the challenge via my blog in this article: http://danicfilip.com/7-day-web-dev-challenge-codepen/
Day 4: no JS today :(. I've been doing some UI studying and decided to do a bit of UI design today by making a dashboard-like menu of some sorts. Then I decided to play a bit with CSS3 animations to make an intrusive and very annoying notification style.
