# Dialog

> A real dialog that grows out of the button that opened it and goes back into it. The alert version asks you to type the name before it deletes anything.

Overlays · dialog, modal, alertdialog, confirm · HTML, CSS, vanilla JS · no dependencies · updated 2026-10-21
Demo: https://kodza.dev/components/modal-component/

Takes the whole screen (or reacts to the page scroll): give it a page, not a small box.

## Files

The code below, served as files: byte for byte what the Kodza site copies (the CSS includes its theme guard).

- [`kodza-modal-component.css`](https://kodza.dev/registry/modal-component/kodza-modal-component.css) · 21.0 KB
- [`kodza-modal-component.js`](https://kodza.dev/registry/modal-component/kodza-modal-component.js) · 9.5 KB
- [`kodza-modal-component.html`](https://kodza.dev/registry/modal-component/kodza-modal-component.html) · 2.5 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-modal-component.css https://kodza.dev/registry/modal-component/kodza-modal-component.css
curl -fsSL --create-dirs -o kodza/kodza-modal-component.js https://kodza.dev/registry/modal-component/kodza-modal-component.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: `.kodza-dialog`
- Variables (set them on the root element itself: it declares its own defaults):
  - `--kz-dialog-bg: #ffffff`
  - `--kz-dialog-fg: #0a0a0a`
  - `--kz-dialog-muted: rgba(10, 10, 10, 0.6)`
  - `--kz-dialog-line: rgba(10, 10, 10, 0.12)`
  - `--kz-dialog-soft: rgba(10, 10, 10, 0.05)`
  - `--kz-dialog-ink: #0a0a0a`
  - `--kz-dialog-on-ink: #ffffff`
  - `--kz-dialog-backdrop: rgba(10, 10, 10, 0.3)`
  - `--kz-dialog-shadow: 0 30px 70px -20px rgba(10, 10, 10, 0.45)`
  - `--kz-dialog-width: 440px`
  - `--kz-dialog-radius: 20px`
  - `--kz-dialog-ease: cubic-bezier(0.22, 1, 0.36, 1)`
- Modifiers: `.kodza-dialog--alert`
- Attributes:
  - `data-confirm` (e.g. `kodza-site`)
- Events: `kodza:close` (bubbling, from the root)
- Lifecycle: `kodza:init` / `kodza:destroy` on `document`, with `{ detail: { root } }` to target a container.

## Keyboard

What each key does, by where the focus is. Keep it working when you adapt the HTML: same elements, same classes.

- On the button (focus in `.kodza-dialog__trigger`):
  - `Enter` / `Space`: Opens it, focus goes into the panel
- In a field (focus in `.kodza-dialog__field`):
  - `Enter`: Runs the main button, once it's enabled
- In the panel (focus in `.kodza-dialog__panel`):
  - `Tab` / `Shift+Tab`: Next or previous control, the page behind is out of reach
- Anywhere, while it's open (while `.kodza-dialog__panel[open]` is on the page):
  - `Escape`: Closes it, focus back on the button

## 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-dialog {
    --kz-dialog-bg: #161616;
    --kz-dialog-fg: #f2f2f0;
    --kz-dialog-muted: rgba(242, 242, 240, 0.62);
    --kz-dialog-line: rgba(255, 255, 255, 0.14);
    --kz-dialog-soft: rgba(255, 255, 255, 0.07);
    --kz-dialog-ink: #f2f2f0;
    --kz-dialog-on-ink: #0a0a0a;
    --kz-dialog-backdrop: rgba(0, 0, 0, 0.55);
    --kz-dialog-shadow: 0 30px 70px -20px rgba(0, 0, 0, 0.9);
  }
}
```

A site with its own theme switch puts the same rules under its dark selector instead (`[data-theme="dark"] .kodza-dialog { … }`); a single dark section, under that section's class.

## Use it

### Plain HTML page

- CSS: `kodza/kodza-modal-component.css` next to the page (the Files commands as they are), linked in `<head>`: `<link rel="stylesheet" href="kodza/kodza-modal-component.css">`. Without a shell, paste it in a `<style>` in `<head>` instead. It only touches `kodza-` classes.
- HTML: where the component goes. Paste it as many times as you need: instances never interfere.
- JS: `kodza/kodza-modal-component.js`, loaded with `<script src="kodza/kodza-modal-component.js" defer></script>` in `<head>`. Without a shell, paste it in a `<script>` before `</body>` (or in `<head>`: it waits for the page). One copy per page, whatever the number of instances.
- Restyle with the `--kz-…` variables, set on the component's root element itself (the root declares its own defaults, so a value on an ancestor is ignored), and with the modifiers / attributes listed under API.
- Font: it takes the page's own. The Kodza look is Geist: `<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Geist:wght@400;500;600;700&family=Geist+Mono:wght@400;500&display=swap">`.
- Content added later (AJAX navigation, a SPA route, a builder preview): start it with `document.dispatchEvent(new CustomEvent('kodza:init', { detail: { root: container } }))`; before removing it, the same call with `'kodza:destroy'` stops it and puts the original markup back.

### Claude artifact (claude.ai)

- Paste the CSS in a `<style>` and the JS in a `<script>` at the end, in the artifact itself: it loads stylesheets only from Google Fonts and scripts only from a few CDNs, so no `<link>` or `<script src>` to Kodza.
- Writing the artifact file with a shell? Insert the downloaded files (Files) with a command instead of retyping them: a line `KODZA-CSS` alone inside the `<style>`, `KODZA-JS` inside the `<script>`, then `sed -e '/^KODZA-CSS$/{r kodza/kodza-modal-component.css' -e 'd' -e '}' -e '/^KODZA-JS$/{r kodza/kodza-modal-component.js' -e 'd' -e '}' page.html > artifact.html`.
- Font: load Geist from Google Fonts (allowed): `<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Geist:wght@400;500;600;700&family=Geist+Mono:wght@400;500&display=swap">`.
- Dark mode: the viewer sets `data-theme="dark"` or `"light"` on `<html>`, or nothing when it follows the system. Write the Dark mode rules twice: inside `@media (prefers-color-scheme: dark)` with `:root:not([data-theme="light"])` in front of each selector, and with `:root[data-theme="dark"]` in front of each selector.
- Forms: there is nowhere to send them. Handle `submit` in your script with `event.preventDefault()` and show the result in the page.

### WordPress

- HTML: a **Custom HTML** block (or a pattern / template part). WordPress keeps this markup as it is only for users allowed to post unfiltered HTML (Administrators; Super Admins on multisite): for anyone else it strips tags such as `<svg>`, `<input>` or `<dialog>`, so add it from the theme (a pattern or template part) instead.
- This one is inline (it flows like a word): pasted alone, many themes leave it at the edge of the page (block themes, and classic ones like Twenty Twenty-One or Blocksy), so put the Custom HTML block inside a **Group** block to line it up with the text.
- CSS and JS: the downloaded files go in the theme, under `wp-content/themes/<your-theme>/kodza/` (the child theme if there is one), enqueued from its functions.php (or a code-snippets plugin):
  ```php
  add_action('wp_enqueue_scripts', function () {
    $dir = get_stylesheet_directory() . '/kodza/';
    $uri = get_stylesheet_directory_uri() . '/kodza/';
    wp_enqueue_style('kodza-modal-component', $uri . 'kodza-modal-component.css', [], filemtime($dir . 'kodza-modal-component.css'));
    wp_enqueue_script('kodza-modal-component', $uri . 'kodza-modal-component.js', [], filemtime($dir . 'kodza-modal-component.js'), true);
  });
  ```
  Scoped to `kodza-` classes, the CSS never touches the theme. One copy of the JS, whatever the number of blocks.
- No access to the theme files? The CSS can also go, as it is, in **Appearance → Customize → Additional CSS** (classic theme) or **Styles → Additional CSS** in the Site Editor (block theme).
- Theme with AJAX page transitions: fire `kodza:init` on the new content after each swap (and `kodza:destroy` on the old one).
- Performance plugin (WP Rocket, LiteSpeed Cache, Perfmatters…) with **Delay JavaScript execution** turned on: add `kodza` to the scripts it must not delay. Otherwise the component waits for the visitor's first scroll, tap or mouse move, and that first click can be lost.
- Colours: by default, match the theme's palette. After the component's CSS, point these variables at the theme's colours, on the component root, Kodza's value as the fallback:
  `.kodza-dialog { --kz-dialog-fg: var(TEXT, #0a0a0a); --kz-dialog-bg: var(BACKGROUND, #ffffff); --kz-dialog-ink: var(ACCENT, #0a0a0a); --kz-dialog-on-ink: var(BACKGROUND, #ffffff); }`
  TEXT, BACKGROUND and ACCENT (the colour the theme fills its own buttons with) are the theme's own colour variables — block themes (theme.json, like Twenty Twenty-Five): `--wp--preset--color--contrast`, `--wp--preset--color--base`, `--wp--preset--color--contrast` (they fill their buttons with it; their accent-1… colours are decorative); Astra: `--ast-global-color-2`, `--ast-global-color-4`, `--ast-global-color-0`; Kadence: `--global-palette3`, `--global-palette9`, `--global-palette1`; GeneratePress: `--contrast`, `--base-3`, `--accent`; Blocksy: `--theme-palette-color-4`, `--theme-palette-color-8`, `--theme-palette-color-1`. Use only these names, and only if the site really has them (the theme's CSS, or Styles → Colors): the `--wp--preset--color--black`, `--white`, `--vivid-…` that WordPress adds everywhere are not the theme's palette. Another theme, or one without these variables (Hello Elementor, OceanWP): leave the variables alone, it keeps Kodza's monochrome; same when the developer asks for monochrome or the Kodza look. Leave the translucent greys (`rgba(10, 10, 10, …)`) as they are: they suit any light background. On a dark palette, set the other variables from Dark mode too.
- WordPress turns straight quotes and `--` into typographic ones in the text of a Custom HTML block (not inside `<code>` or `<pre>`).

#### With Elementor

- HTML: an **HTML** widget (Elementor shows it to administrators only). It keeps the code exactly as pasted, straight quotes included.
- CSS and JS: as above. Elementor's Site Settings → Theme Style styles every button, field, link and image of the page, components included; the theme guard at the end of the CSS keeps the component's buttons, fields and link colours as they are.
- The Elementor editor redraws each widget after the page has loaded: without the script below, the component stays still in the editor preview (the published page works). Add it once per site, in the footer like the component's script (`kodza/elementor-editor.js`, or a code-snippets plugin):

```js
// Kodza in the Elementor editor: the editor redraws each HTML widget after the page has loaded.
// Start Kodza in what it draws, stop it in what it replaces or removes. Once per site.
window.addEventListener('elementor/frontend/init', () => {
  if (!elementorFrontend.isEditMode()) return;
  class KodzaWidget extends elementorModules.frontend.handlers.Base {
    onInit() {
      super.onInit();
      this.kodza = [...this.$element[0].children];
      document.dispatchEvent(new CustomEvent('kodza:init', { detail: { root: this.$element[0] } }));
    }
    onDestroy() {
      super.onDestroy();
      this.kodza.forEach((root) => document.dispatchEvent(new CustomEvent('kodza:destroy', { detail: { root } })));
    }
  }
  elementorFrontend.elementsHandler.attachHandler('html', KodzaWidget);
});
```

- No child theme: everything can go in the HTML widget instead, `<style>` with the CSS, the HTML, then `<script>` with the JS. It works on the page and in the editor without the script above.

### Shopify

- Files: `assets/kodza-modal-component.css` and `assets/kodza-modal-component.js` (the Files commands with `-o assets/…`).
- In the section: `{{ 'kodza-modal-component.css' | asset_url | stylesheet_tag }}` and `<script src="{{ 'kodza-modal-component.js' | asset_url }}" defer></script>`, then the HTML.
- The theme editor re-renders sections: restart them with
  `document.addEventListener('shopify:section:load', (e) => document.dispatchEvent(new CustomEvent('kodza:init', { detail: { root: e.target } })));`
  and the same with `shopify:section:unload` → `kodza:destroy`.

### React / Next.js

- Files, side by side (e.g. in `components/kodza/`): `Dialog.tsx` (below), the CSS block under Code saved as `modal-component.css` and the JS block as `modal-component.js`, both as they are. The HTML block is already inside the component: skip it.
- Use it: `import { Dialog } from '@/components/kodza/Dialog';` then `<Dialog />`. Props: `variant` ("alert", or several in an array), `confirm` (`data-confirm`: "kodza-site"), `vars` (the `--kz-…` variables listed under API, e.g. `vars={{ '--kz-dialog-bg': … }}`), `onClose` (the `kodza:close` event), `className`, `style` and the other props of its `<div>` (`onClick`, `aria-…`).
- Next.js App Router: it is a Client Component already (`'use client'`). Pages Router: Next.js takes global CSS only in `pages/_app`, so move the `import './modal-component.css'` line there.
- Safe under StrictMode, client-side navigation and prop changes: when a prop changes, the `key` gives React a fresh element, `kodza:destroy` stops the script on the old one and `kodza:init` starts it on the new one.

```tsx
'use client';
// Kodza — Dialog, for React. From https://kodza.dev/components/modal-component/
// Kodza License: free to use, client work included. Not to resell or redistribute, ported or not: https://kodza.dev/docs/#print-license
// Next to this file: modal-component.css and modal-component.js, the component's CSS and JS from Kodza, as they are.
// Yours to edit: the markup is plain JSX below.
// The script changes this markup once React has rendered it (it adds layers, splits text, moves
// nodes), so React must not patch it afterwards. When a prop changes, the key gives React a fresh
// element: kodza:destroy stops the script on the old one, kodza:init starts it on the new one.

// Opens the <dialog> out of its trigger (the panel scales from the button's position) and sends
// it back there on close, whatever closes it: a button of the form (method="dialog"), Escape, or
// a click on the page. The alert version (--alert) is an alertdialog: a click on the page makes
// it insist instead of closing, and its main button waits for the name in data-confirm.
// Fires "kodza:close" with { value } (the button's value, or "cancel").
