HTML and CSS are often underestimated. Developers who truly master them build frontends that work with very little JavaScript, have fast build times without CSS compilation, rely on more dependable browser APIs, behave correctly in screen readers, and hold together across every screen size. Semantic markup is the foundation for accessibility, SEO, and long-term maintainability.

Modern CSS features like Container Queries, Custom Properties, Anchor Positioning, Cascade Layers, and has() — alongside current Web APIs like Popover, View Transitions, or WebTransport — enable user experiences and capabilities that would have required complex JavaScript just a few years ago.
