Josh Comeau

Josh W. Comeau writes in-depth, interactive tutorials on CSS, React and animation for front-end developers, on subjects such as anchor positioning, subgrid, scroll-driven animation timelines and sprite animation. Posts embed live demos and playgrounds you can edit, and he also teaches the courses CSS for JavaScript Developers and The Joy of React. Start with his comparison of JavaScript animation libraries against CSS transitions and keyframes, or the post on using Disney's first principle of animation for SVG micro-interactions.
