Discussion on: Why doesn't CSS move faster (like JavaScript)?

First of all, I think we need to challenge your question: does CSS really evolve slower than JavaScript? Recent major developments (Grid layout, Flexbox, Picture specification, Houdini...) have radically changed the way style sheets are produced today. So I think CSS is evolving very fast.

Some may consider that the language itself scarcely evolves. But compared to JavaScript, the language is incredibly simple and above all, its interpretation is blazingly fast. JavaScript code has an incredibly high cost of parsing and interpretation and we are very far from being able to do the same thing in JS and CSS with the same file size. IMHO, the simplicity of CSS is its strength.
