I love the fact that CSS is finally reclaiming control over visual interactions, taking charge of the styling, the animation, and the accessibility exactly as it should. Today, native browser capabilities allow us to move the heavy lifting away from the JavaScript main thread and closer to the GPU. By letting the browser’s engine optimize performance under the hood, we save energy and processing power while building code that is robust, accessible, and independent of external libraries that might deprecate tomorrow.

We have 3D, modern layout techniques, clip-paths, transforms, custom properties, scroll-driven animations, view-transitions, @property — and we can animate almost anything, even to auto-height!

And, of course, there’s SVG, which isn’t new, but allows us to build entire websites through illustrations and animations. Take the example below: it’s responsive, lightweight, accessible, and powered primarily by CSS Grid + SVG.

We can even build an entire video game including the UI using only SVG:

What follows is not a complete guide to modern CSS, but an opinionated selection of techniques I reach for when I want a site to feel alive and be remembered. There are many ways to create memorable experiences. Sometimes it’s as simple as a form that completes smoothly. But here I’m interested in the expressive end of the spectrum.
