CSS Driven Chat in Sketch

I found an article on Medium, written by Matej Hrescak called: "Exploring Dynamic Layout in Sketch" which I found a bit crazy (but exiting as well) first because you design with CSS (flex to be exact) so I gave it a try and it is an awesome method, no pixel pushing or resizing and you can modify the symbols however you want without duplicating them. Pretty fun, try it out!
