ds.css

ds.css makes your web page look like a Nintendo DS. It is a small CSS framework that recreates the DS and DS Lite interface, the chunky buttons, the dual-screen chrome, the whole handheld aesthetic, as drop-in styles and web components. MIT-licensed and free, add it with one CDN link or an npm install.

There is no build step and no ops, it is a stylesheet. Pull it from unpkg with a link tag, grab the files from dist, or install the npm package, and you are styling. That simplicity is the point: this is a theme, not a framework you architect an app around.

Be clear-eyed about what this is, a novelty. It is a hobby project for building something with retro-console charm, a personal site, a game-jam entry, a portfolio piece with personality. For anything users rely on daily, reach for a real design system like Tailwind, Pico, or shadcn. For fun, ds.css delivers exactly what it promises.

The catch is longevity and scope. It covers parts of the DS UI, not a complete component set, and it carries the activity profile of a passion project, not production tooling. Great for a weekend build, risky as a foundation.
