In plain English

iCSS, by the author chokcoco, is a learning repository devoted to CSS and web animation. The name and tagline (which translate roughly as "not just CSS") point at the spirit: it is not a library you install, but an ongoing collection of articles, demos, and tricks that explore what you can do with modern CSS in the browser. The README is in Chinese; the author also publishes the same material to a personal blog. The unusual thing about this repo is where the content lives. Rather than folders and markdown files, every article is published as a GitHub Issue, and the Issues are organised through labels so readers can browse by topic. The label list gives a sense of scope, backgrounds, borders, clip-path (which crops elements into custom shapes), masks, shadows, shape effects, blend modes, filters, pseudo-classes, layout, CSS functions, CSS Houdini (a low-level API for extending CSS), variables, modern CSS features, CSS-doodle, animation, accessibility, 3D, image and text effects, SVG, performance, browser-specific features, UX, design, and interview prep. Each entry is typically a short walkthrough of a visual effect with explanations of how and why the CSS works, accompanied by GIFs or screenshots. The numbered list in the README runs into the 200s, covering things like Anchor Positioning, complex button shapes, gradient borders, hover effects, scroll-driven colour transitions, the :has() selector, and accent-color. It is aimed at front-end developers who want to deepen their CSS skills or pick up creative techniques. The repo's primary listed language is JavaScript, used in some demo snippets. The full README is longer than what was provided.
