Today, native browser capabilities allow us to move the heavy lifting away from the JavaScript main thread and closer to the GPU.

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.

Everything communicates, and our animations are no exception. We must take the time to design movements that support the message we want to convey in order to keep our intents tightly scoped without overdoing it. Here’s a methodology I use when planning the design and animation of a site. Imagine we’re working on a project for a nature event focused on mushrooms
