If you are a web developer coding with CSS is fundamental. Sadly the old 2D shapes can be quite boring at times.
Although CSS did support 3D for more than a decade it was super hard to understand and code.
So I decided to make a 3D css library to make coding on 3D really simple.

I have just started working on it and right now it's limited to cuboids and cubes. But do check it out on github.
