There's work CSS scoping going on as well. https://drafts.csswg.org/css-scoping-2/ https://drafts.csswg.org/css-scoping-2/ Yet another thing Miriam Suzanne has been working on is a proposal for CSS Layers. I think it's a way of declaring what styles should "win" when specificity is equal instead of "last one loaded wins" or using the very crude `!important` tool. This could be particularly helpful if stylesheets for 3rd party components are loaded dynamically or on platforms where the style author doesn't have absolute control over stylesheet order. https://drafts.csswg.org/css-cascade-5/ https://drafts.csswg.org/css-cascade-5/ All of these will take some time to get right and then some patience for older browsers to die off (or decent fallback strategies, I think all these would be hard to polyfill).
