雲吞麵 Midnight Wonton Noodle — Pure CSS Art

This is a submission for Frontend Challenge: Comfort Food Edition , CSS Art: Comfort Food. What I Built A pure CSS art scene of the ultimate Hong Kong comfort food: a steaming bowl of wonton noodle soup (雲吞麵) at a late-night dai pai dong. Nothing says "home" to me like a midnight bowl of wonton noodles under a glowing paper lantern — so I recreated that feeling entirely in CSS: no images, no SVG, just divs, gradients, border-radius tricks, and keyframe animations. The scene includes: 🥣 A classic HK porcelain bowl with the iconic blue rim stripe pattern (repeating-linear-gradient) 🍜 Golden broth with a noodle nest built from repeating-radial-gradient concentric arcs 🥟 Four pleated wontons, half-submerged at the broth line 🥢 Wooden chopsticks resting across the rim (tapered with clip-path) ♨️ Soft, organic steam wisps — blurred gradient blobs on staggered transform/opacity loops 🏮 A swaying red paper lantern casting a warm light cone 🌙 Moon, twinkling stars, bokeh lights, a flickering pink neon 雲吞麵 sign, chili oil saucer, and a cup of tea Demo zsp67x2nfnudg.kimi.page 👆 Live full-screen demo — watch the steam rise, the lantern sway, and the neon sign flicker.

Journey Design goal: I wanted the warmth of the lantern light to contrast against the cool indigo night, with a subtle purple dusk at the horizon — the exact feeling of sitting at a Hong Kong street stall at 1am. Techniques I'm proud of: The steam was the hardest part. Thin wisps disappeared against the sky, so I layered blurred radial-gradient blobs (13% wide, filter: blur) with keyframes that hold a long visible opacity plateau (0 → .7 → .65 → .38 → 0). Four wisps run on two different periods (6s / 7.2s) with delays locked 25% of a cycle apart, so at least one wisp is always near peak — the bowl never stops steaming. The bowl is a single div with border-radius: 0 0 50% 50% / 0 0 100% 100% for the porcelain body; the broth ellipse's own border d
