# Copy to Clipboard
> A command, or a sentence for your AI, with a copy button: the icon turns into a check that draws itself and the label rolls to "Copied".

## Files
The code below, served as files: byte for byte what the Kodza site copies (the CSS includes its theme guard).
- [`kodza-copy-clipboard.css`](https://kodza.dev/registry/copy-clipboard/kodza-copy-clipboard.css) · 10.5 KB
- [`kodza-copy-clipboard.js`](https://kodza.dev/registry/copy-clipboard/kodza-copy-clipboard.js) · 3.5 KB
- [`kodza-copy-clipboard.html`](https://kodza.dev/registry/copy-clipboard/kodza-copy-clipboard.html) · 1.7 KB · the markup, to adapt and paste into your page
**Can you run shell commands? Download the CSS and the JS, don't retype them.** Retyping costs thousands of tokens and can drop or change lines of the CSS. Put the files where your stack expects them (Use it says where: change the `-o` paths):
```bash
curl -fsSL --create-dirs -o kodza/kodza-copy-clipboard.css https://kodza.dev/registry/copy-clipboard/kodza-copy-clipboard.css
curl -fsSL --create-dirs -o kodza/kodza-copy-clipboard.js https://kodza.dev/registry/copy-clipboard/kodza-copy-clipboard.js
```
Then load the files from your page as Use it shows, instead of pasting the content. The HTML is the part you adapt (text, links, modifiers): paste it from the Code section. Copy the CSS and the JS from the Code section only if you can't run commands, exactly as they are. (Windows PowerShell: `curl.exe`.)
## API
- Root: `[data-kodza-copy]`
- Variables (set them on the root element itself: it declares its own defaults):
- `--kz-copy-bg: #ffffff`
- `--kz-copy-fg: #0a0a0a`
- `--kz-copy-muted: rgba(10, 10, 10, 0.45)`
- `--kz-copy-border: rgba(10, 10, 10, 0.1)`
- `--kz-copy-button-bg: #0a0a0a`
- `--kz-copy-button-fg: #ffffff`
- `--kz-copy-radius: 14px`
- `--kz-copy-font: ui-monospace, "SF Mono", "Geist Mono", Menlo, monospace`
- `--kz-copy-size: 14px`
- `--kz-copy-prompt: "$ "`
- `--kz-copy-button-height: 38px`
- `--kz-copy-max-width: 520px`
- `--kz-copy-duration: 0.45s`
- `--kz-copy-ease: cubic-bezier(0.22, 1, 0.36, 1)`
- Modifiers: `.kodza-copy--prompt`
- Attributes:
- `data-kodza-copy`
- Lifecycle: `kodza:init` / `kodza:destroy` on `document`, with `{ detail: { root } }` to target a container.
## Dark mode
The values Kodza uses on a dark background (`#0a0a0a`). For a page that follows the system theme, add them after the component's CSS:
```css
@media (prefers-color-scheme: dark) {
.kodza-copy {
--kz-copy-bg: #161616;
--kz-copy-fg: #f2f2f0;
--kz-copy-muted: rgba(255, 255, 255, 0.45);
--kz-copy-border: rgba(255, 255, 255, 0.1);
--kz-copy-button-bg: #ffffff;
--kz-copy-button-fg: #0a0a0a;
}
}
```
A site with its own theme switch puts the same rules under its dark selector instead (`[data-theme="dark"] .kodza-copy { … }`); a single dark section, under that section's class.
## Use it
### Plain HTML page
- CSS: `kodza/kodza-copy-clipboard.css` next to the page (the Files commands as they are), linked in ``: ``. Without a shell, paste it in a `
