Let me address that by combining my two favourite topics: CSS and performance. Broadly speaking, this is why CSS is so key to performance: A browser can’t render a page until it has built the Render Tree; the Render Tree is the combined result of the DOM and the CSSOM; the DOM is HTML plus any blocking JavaScript that needs to act upon it; the CSSOM is all CSS rules applied against the DOM; it’s easy to make JavaScript non-blocking with async and defer.
