Splitting your code across technology boundaries is a misapplication of "separation of concerns". The "component" concept of React and other front-end frameworks seems to be a much better abstraction. Styles work very well on the per-component level. The best and worst part of CSS is the "cascading" part. The thing is that with React, you aren't really writing HTML. Sure, JSX makes it look like it, but it's not a template, it's actually just a Virtual DOM element tree. This means it doesn't have the same issues as many templates.
