Write and refactor Vue, React, Svelte, Blade, and HTML with vite-plugin-useclassy (UseClassy) modifier attributes: class:hover, class:focus, class:sm, class:md, class:dark, className:hover, className:focus, class:sm:hover, and similar. Use when authoring UI, writing Tailwind or UnoCSS hover/focus/responsive/dark variants, converting hover: focus: sm: md: prefixes into UseClassy attributes, refactoring className variant tokens, or reviewing and fixing UseClassy markup.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Authoring with UseClassy

Use UseClassy to separate Tailwind variants from base utilities:

```html
<!-- Before -->
<button class="rounded px-4 hover:bg-blue-500 hover:text-white focus:ring-2">

<!-- After -->
<button
  class="rounded px-4"
  class:hover="bg-blue-500 text-white"
  class:focus="ring-2"
>
```

| ----------- | --------------- | ----------------------------------------------------------------------- |
| Vue / Blade | `class="…"`     | `class:hover="…"`, `class:sm:hover="…"`                                 |
| React       | `className="…"` | `className:hover="…"`, `className:@md="…"`, `className:group-hover/item="…"`, `className:[&>*]="…"`, `className:data-[state=open]="…"`; JSX expressions allowed |
| Svelte      | `class="…"`     | Quoted only: `class:hover="…"`                                          |

How to install

The exact contents, by fingerprint
mdr add jrmybtlr/useclassy/useclassy@sha256:a6d6742b5596d907

The line at the top of this page pins the label git:20260905.27ad110, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
