Y2K UI

Modern Y2K / kawaii-retro components for the web. Flat windows, thick navy outlines, pastel fills. No glassmorphism. No Win98 bevel. No neobrutalism offset shadow.

Quick start

What's inside

• Flat window chrome — title bar + [_ ▢ ✕] controls, thick 2-3px navy border.
• Pastel palette — blue #8ed1fc, pink #ff8fcf, lilac #b69cff, mint #8ff0d0, lemon #ffe45e.
• Crisp 4-8px radius — no pill blobs.
• Zero hard offset shadow — the border IS the structure.
