Art Deco is the design language of the 1920s and 30s — the era of jazz clubs, ocean liners, and skyscrapers going up for the first time. Gold accents, geometric symmetry, bold vertical lines, and a sense of occasion that makes everything it touches feel more important than it probably is. Nobody is doing this in web apps right now, which means if you do it well, your product is instantly the most visually distinctive thing in whatever category you're in.
ArtDeco.
The design language of the 1920s — gold accents, geometric symmetry, bold vertical lines, and a sense of occasion that makes everything it touches feel more important.
Symmetry is respect
Art Deco treats symmetry as a form of dignity — the idea that a well-ordered composition shows respect for whoever's looking at it. Everything is centered, mirrored, or deliberately balanced. You won't find the casual asymmetry of modern web design here; instead you get layouts that feel like they were measured twice before anything was placed.
Gold doesn't mean gaudy
The gold in Art Deco isn't there to show off — it's there to catch light. Used sparingly, on borders, dividers, key typographic elements, and decorative details, it creates a warmth and material quality that no other accent color can replicate. The moment you use it everywhere, it tips into tacky. The discipline is knowing where to stop.
Geometry is the ornament
Where other historical styles used floral patterns and organic curves as decoration, Art Deco used geometric precision — sunbursts, chevrons, stepped forms, radiating lines. The decoration is built from the same design vocabulary as the structure, which is why it feels cohesive rather than applied. Every decorative element looks like it was drawn with a ruler, not a brush.
Before building with Claude Code, drop SKILL.md and DESIGN.md into Claude Design first. Use it to generate mockups and nail the visual direction — then hand those references to Claude Code. You'll get significantly higher quality output than going straight to code.
Minimal Serif
Large confident serifs, generous whitespace, restrained palette — looks like a designer was involved even when one wasn't.
Dark Luxury
Deep warm darks, confident typography, one electric accent — the visual language of apps that cost money and look like it.
Two files. That's it.
Drop them into your Claude project or Cursor rules and build normally. No CLI, no package manager, no setup.
