How to use Neon Frame
Paste the HTML where you need it and the CSS into a global stylesheet (or a <style> tag). Every class is prefixed nuda- so it never collides with Tailwind or your own styles. Tweak the CSS custom properties to match your design system.
Works in React, Vue, Svelte, Astro, Next.js, Nuxt, Laravel Blade, Django, Rails — or a single .html file. No npm install, no build step.
