chokcoco/CSS-Inspiration ? reverse-engineered prompt

Build me a clean Chinese CSS inspiration website that collects lots of small CSS tricks and demo pages, grouped by topic like layout, shadows, pseudo elements, filters, borders, backgrounds, text, SVG, and animations.

I want it to feel like a handy gallery where someone can quickly browse ideas, open a demo, and learn how each effect works. The home page should show the categories clearly, with a simple sidebar or menu for navigating between examples. Each example page should have a live looking preview area and a short explanation, so people can understand the effect without digging too much.

Make it lightweight, fast, and easy to add more examples later. Keep the style polished but not distracting, since the main point is the CSS effects themselves. If you need to look up current docs or best practices online, go ahead.
