CSS grids are a layout revolution. Quite difficult to learn, but very powerful. It may take years before the community understands all that it has to offer. Container queries are a game changer, although not fully ready across browsers yet. CSS variables have been around for a while now, but still considered fairly new. CSS nesting is also around the corner. When you combine these two things, you can start considering to drop CSS preprocessors like SCSS. CSS layers is brand new and may be useful when working with design language systems. And as an unimportant but fun last one: you can now address colors outside the RGB color space.
