# Date Range

> Two real date inputs behind one field and a two-month calendar: the ink band follows the pointer from the start to the end, the length counted as it goes, with optional shortcuts. Full keyboard.

## Files

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

- [`kodza-date-range.css`](https://kodza.dev/registry/date-range/kodza-date-range.css) · 28.9 KB
- [`kodza-date-range.js`](https://kodza.dev/registry/date-range/kodza-date-range.js) · 32.6 KB
- [`kodza-date-range.html`](https://kodza.dev/registry/date-range/kodza-date-range.html) · 1.0 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-date-range.css https://kodza.dev/registry/date-range/kodza-date-range.css
curl -fsSL --create-dirs -o kodza/kodza-date-range.js https://kodza.dev/registry/date-range/kodza-date-range.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-date-range`
- Variables (set them on the root element itself: it declares its own defaults):
  - `--kz-date-range-bg: #ffffff`
  - `--kz-date-range-fg: #0a0a0a`
  - `--kz-date-range-muted: rgba(10, 10, 10, 0.6)`
  - `--kz-date-range-line: rgba(10, 10, 10, 0.14)`
  - `--kz-date-range-line-hover: rgba(10, 10, 10, 0.3)`
  - `--kz-date-range-soft: rgba(10, 10, 10, 0.06)`
  - `--kz-date-range-band: rgba(10, 10, 10, 0.07)`
  - `--kz-date-range-ink: #0a0a0a`
  - `--kz-date-range-on-ink: #ffffff`
  - `--kz-date-range-shadow: 0 18px 40px -16px rgba(10, 10, 10, 0.3)`
  - `--kz-date-range-height: 56px`
  - `--kz-date-range-radius: calc(12px * var(--kz-radius-scale, 1))`
  - `--kz-date-range-pad: 16px`
  - `--kz-date-range-cell: 38px`
  - `--kz-date-range-gap: 24px` — between the two months
  - `--kz-date-range-ease: cubic-bezier(0.22, 1, 0.36, 1)`
  - `--kz-date-range-width: var(--kz-field-width, 360px)`
- Attributes:
  - `data-date`
  - `data-locale` (e.g. `en-GB`, `en-US`)
  - `data-months`
  - `data-preset`
  - `data-presets` (e.g. `last-7 last-30 this-month last-month`)
  - `data-step` (e.g. `-1`, `1`)
  - `data-unit` (e.g. `night`)
  - `data-week-start`
- 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 a day of the calendar (focus in `.kodza-date-range__day`):
  - `ArrowLeft` / `ArrowRight`: Previous or next day
  - `ArrowUp` / `ArrowDown`: Previous or next week
  - `Home` / `End`: First or last day of the week
  - `PageUp` / `PageDown`: Previous or next month
  - `Enter` / `Space`: Picks the start, then the end, and closes
- On the field (focus in `.kodza-date-range__half`):
  - `Enter` / `Space`: Opens the calendar on that date
- Anywhere, while it's open (while `.kodza-date-range.is-open` is on the page):
  - `Escape`: Closes it, focus back on the field

## 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-date-range {
    --kz-date-range-bg: #161616;
    --kz-date-range-fg: #f2f2f0;
    --kz-date-range-muted: rgba(242, 242, 240, 0.62);
    --kz-date-range-line: rgba(255, 255, 255, 0.14);
    --kz-date-range-line-hover: rgba(255, 255, 255, 0.3);
    --kz-date-range-soft: rgba(255, 255, 255, 0.08);
    --kz-date-range-band: rgba(255, 255, 255, 0.09);
    --kz-date-range-ink: #f2f2f0;
    --kz-date-range-on-ink: #0a0a0a;
    --kz-date-range-shadow: 0 18px 40px -16px rgba(0, 0, 0, 0.8);
  }
}
```

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

## Use it

### Plain HTML page

- CSS: `kodza/kodza-date-range.css` next to the page (the Files commands as they are), linked in `<head>`: `<link rel="stylesheet" href="kodza/kodza-date-range.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-date-range.js`, loaded with `<script src="kodza/kodza-date-range.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. A site with its own type sets it once for every Kodza component, on `:root`, never by editing the CSS (unset, nothing changes): `--kz-font-label`, the face of the small labels (meta, captions, counters, hints, footer links, button labels); `--kz-font-label-size`, their size, one for all of them (`11px`…); `--kz-font-label-weight`, their weight; `--kz-font-label-tracking`, their letter-spacing; `--kz-font-label-case`, their case (`uppercase`…; code and units keep theirs); `--kz-font-label-leading`, their line-height (`1.45`…; buttons, pills and keys keep their box); `--kz-font-mono`, the monospace face (code, labels, counters). 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">`.
- Corners: a site with its own shapes sets them once for every Kodza component, on `:root`, never by editing the CSS (unset, nothing changes): `--kz-radius-scale` multiplies every corner (`0` square, `0.5` softer, `1` Kodza); `--kz-radius-pill` sets the pills (`0` squares them).
- Width: a form sets it once for every Kodza field, on the form or on `:root` (`--kz-field-width: 100%` fills the column). Unset, nothing changes.
- Motion: a site sets its pace once for every Kodza component, on `:root`, never by editing the CSS or the JS: `--kz-motion-scale` multiplies every duration (`0.5` twice as fast, `2` twice as slow, `0` no motion at all, loops stopped, like reduced motion). Unset, nothing changes.
- 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$/{r kodza/kodza-date-range.css' -e 'd' -e '}' -e '/^KODZA-JS$/{r kodza/kodza-date-range.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">`. A site with its own type sets it once for every Kodza component, on `:root`, never by editing the CSS (unset, nothing changes): `--kz-font-label`, the face of the small labels (meta, captions, counters, hints, footer links, button labels); `--kz-font-label-size`, their size, one for all of them (`11px`…); `--kz-font-label-weight`, their weight; `--kz-font-label-tracking`, their letter-spacing; `--kz-font-label-case`, their case (`uppercase`…; code and units keep theirs); `--kz-font-label-leading`, their line-height (`1.45`…; buttons, pills and keys keep their box); `--kz-font-mono`, the monospace face (code, labels, counters).
- Corners: a site with its own shapes sets them once for every Kodza component, on `:root`, never by editing the CSS (unset, nothing changes): `--kz-radius-scale` multiplies every corner (`0` square, `0.5` softer, `1` Kodza); `--kz-radius-pill` sets the pills (`0` squares them).
- Width: a form sets it once for every Kodza field, on the form or on `:root` (`--kz-field-width: 100%` fills the column). Unset, nothing changes.
- Motion: a site sets its pace once for every Kodza component, on `:root`, never by editing the CSS or the JS: `--kz-motion-scale` multiplies every duration (`0.5` twice as fast, `2` twice as slow, `0` no motion at all, loops stopped, like reduced motion). Unset, nothing changes.
- 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.
- 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-date-range', $uri . 'kodza-date-range.css', [], filemtime($dir . 'kodza-date-range.css'));
    wp_enqueue_script('kodza-date-range', $uri . 'kodza-date-range.js', [], filemtime($dir . 'kodza-date-range.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: it takes the colour of the text around it (or keeps its own monochrome): nothing to point at the theme.
- 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-date-range.css` and `assets/kodza-date-range.js` (the Files commands with `-o assets/…`).
- In the section: `{{ 'kodza-date-range.css' | asset_url | stylesheet_tag }}` and `<script src="{{ 'kodza-date-range.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/`): `DateRange.tsx` (below), the CSS block under Code saved as `date-range.css` and the JS block as `date-range.js`, both as they are. The HTML block is already inside the component: skip it.
- Use it: `import { DateRange } from '@/components/kodza/DateRange';` then `<DateRange />`. Props: `locale` (`data-locale`: "en-GB", "en-US"), `unit` (`data-unit`: "night"), `presets` (`data-presets`: "last-7 last-30 this-month last-month"), `vars` (the `--kz-…` variables listed under API, e.g. `vars={{ '--kz-date-range-bg': … }}`), `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 './date-range.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.
- Built from your data (tabs, rows, options)? Add what the markup is made of to the `key`, as plain values (ids, text, numbers). What the visitor changes (the open tab, the sort, what they type) is the script's: follow it with `onClick` or `onInput` on the root, and change it from your code as a visitor would (click the tab; set the field's value, then dispatch a bubbling `input` event). Fields stay uncontrolled (`defaultValue`, `name`).

```tsx
'use client';
// Kodza — Date Range, for React. From https://kodza.dev/components/date-range/
// 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: date-range.css and date-range.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.
// data-kodza-manual keeps the script from starting it on its own: the effect below does, once
// React has hydrated the markup (on a page that streams in, the script can load first).
// Built from your data (tabs, rows, options)? Put what the markup is made of in the key, as plain
// values (ids, text, numbers): a change starts the script again on fresh markup. What the visitor
// changes (the open tab, the sort, what they type) is the script's: keep it out of the key, follow
// it with onClick or onInput on the root, and change it from your code as a visitor would (click
// the tab; set the field's value, then dispatch a bubbling input event).

// Kodza — Date Range
// Builds one field and a calendar of two months over two real <input type="date"> (the start,
// then the end) and keeps them in step (firing "input" and "change" on them). A click on a day
// sets the start, then the ink band follows the pointer to the end, the length shown as it
// goes: what you see is what the next click takes. data-unit="night" counts nights (a stay: the
// end comes after the start), days otherwise. Shortcuts with data-presets="last-7 last-30 …"
// (the list is in PRESETS), data-months="1" for one month (one on a narrow screen anyway),
// weeks start on Monday (data-week-start="0" for Sunday), names come from data-locale (or the
// page language), min and max are read on the inputs. Arrows move by day and week, Page Up /
// Down by month, Home / End to the start and end of the week, Enter picks, Escape closes and
// gives the focus back. The words and timings are below; each word can be set per field with
// data-text-<name> (data-text-empty="…", data-text-last-7="…"), {n} is filled in.
