Recently I stumbled upon this guy on Twitter and started following him. He explains CSS so well and keeps sharing his CSS Art. I have always been fascinated by how people are able to build beautiful things just using CSS. But I have been solely involved with working in JavaScript writing libraries in the past few years which involved negligible CSS.
With a lot of time in my hands now, I thought of working on one such art just to understand what is behind that magic :)
I picked this piece from Pratham's twitter and started working on it. This was a an entirely different experience. You have to visualize how you can make use of Box Model in a creative way to make various shapes. This is like applying a lot of HACKS but you get beautiful results with that :)
