CSS Houdini is a complete game changer for CSS. It allows you to do things that I never thought would be possible. You can write your own JavaScript to create custom CSS layout and background methods. You can also create your own custom CSS properties on top of many other features. Houdini will singlehandedly change CSS in a far greater way than even flexbox or grid could.
