# Hero Screen

> A centred title and its buttons over a screenshot of the product, leaning back in perspective. On scroll the screen stands up to face you and grows while the title steps back.

Hero · hero, section, landing, saas, screenshot, product, perspective, 3d, scroll, sticky, scrub · HTML, CSS, vanilla JS · no dependencies · updated 2026-10-23
Demo: https://kodza.dev/components/hero-screen/

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-hero-screen.css`](https://kodza.dev/registry/hero-screen/kodza-hero-screen.css) · 18.0 KB
- [`kodza-hero-screen.js`](https://kodza.dev/registry/hero-screen/kodza-hero-screen.js) · 12.5 KB
- [`kodza-hero-screen.html`](https://kodza.dev/registry/hero-screen/kodza-hero-screen.html) · 2.0 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-hero-screen.css https://kodza.dev/registry/hero-screen/kodza-hero-screen.css
curl -fsSL --create-dirs -o kodza/kodza-hero-screen.js https://kodza.dev/registry/hero-screen/kodza-hero-screen.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-hero-screen`
- Variables (set them on the root element itself: it declares its own defaults):
  - `--kz-hero-screen-ink: #0a0a0a`
  - `--kz-hero-screen-paper: #f2f2f0`
  - `--kz-hero-screen-dim: rgba(10, 10, 10, 0.62)`

  - `--kz-hero-screen-bg: transparent`
  - `--kz-hero-screen-bezel: #fff` — the frame around the screenshot
  - `--kz-hero-screen-edge: rgba(10, 10, 10, 0.1)`
  - `--kz-hero-screen-shadow-far: 0 60px 110px -34px rgba(10, 10, 10, 0.34), 0 24px 48px -24px rgba(10, 10, 10, 0.16)` — leaning back
  - `--kz-hero-screen-shadow-near: 0 1px 2px rgba(10, 10, 10, 0.06), 0 22px 48px -22px rgba(10, 10, 10, 0.24)` — upright
  - `--kz-hero-screen-veil: linear-gradient(rgba(10, 10, 10, 0.14), rgba(10, 10, 10, 0.03) 70%)` — the shade on the screen while it leans
  - `--kz-hero-screen-width: 1240px`
  - `--kz-hero-screen-gutter: clamp(16px, 4vw, 40px)`
  - `--kz-hero-screen-pad-y: clamp(20px, 3svh, 40px)`
  - `--kz-hero-screen-size: clamp(36px, min(6.4cqi, 9.4svh), 96px)` — the title lines
  - `--kz-hero-screen-ratio: 1.6` — the screenshot's width / height
  - `--kz-hero-screen-tilt: 24deg` — how far the screen leans back at rest
  - `--kz-hero-screen-shrink: 0.86` — its scale at rest: it grows to full size
  - `--kz-hero-screen-depth: 1600px` — the perspective: shorter is stronger
  - `--kz-hero-screen-radius: 18px`
  - `--kz-hero-screen-top: 0px` — height of a fixed site header: the scene pins under it
  - `--kz-hero-screen-distance: 140svh` — how long the scene holds
  - `--kz-hero-screen-mono: "Geist Mono", ui-monospace, SFMono-Regular, Menlo, monospace`
  - `--kz-hero-screen-ease: cubic-bezier(0.22, 1, 0.36, 1)`
- 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 button (focus in `.kodza-hero-screen__button`):
  - `Enter`: Follows the link
- Tabbing back in:
  - `Shift+Tab`: Lands on a button, the hero scrolls back to show it whole

## 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-hero-screen {
    --kz-hero-screen-ink: #f2f2f0;
    --kz-hero-screen-paper: #0a0a0a;
    --kz-hero-screen-dim: rgba(242, 242, 240, 0.64);
    --kz-hero-screen-faint: rgba(242, 242, 240, 0.5);
    --kz-hero-screen-soft: rgba(242, 242, 240, 0.1);
    --kz-hero-screen-bezel: #161616;
    --kz-hero-screen-edge: rgba(255, 255, 255, 0.12);
    --kz-hero-screen-shadow-far: 0 60px 110px -34px rgba(0, 0, 0, 0.7), 0 24px 48px -24px rgba(0, 0, 0, 0.5);
    --kz-hero-screen-shadow-near: 0 1px 2px rgba(0, 0, 0, 0.4), 0 22px 48px -22px rgba(0, 0, 0, 0.6);
    --kz-hero-screen-veil: linear-gradient(rgba(0, 0, 0, 0.34), rgba(0, 0, 0, 0.08) 70%);
  }
}
```

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

Its images have dark versions next to them (`kz-grid-2400.webp` → `kz-grid-dark-2400.webp`). To swap them on a dark page: `<picture><source media="(prefers-color-scheme: dark)" srcset="…-dark-….webp"><img …></picture>`.

## Use it

### Plain HTML page

- CSS: `kodza/kodza-hero-screen.css` next to the page (the Files commands as they are), linked in `<head>`: `<link rel="stylesheet" href="kodza/kodza-hero-screen.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-hero-screen.js`, loaded with `<script src="kodza/kodza-hero-screen.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$/{r kodza/kodza-hero-screen.css' -e 'd' -e '}' -e '/^KODZA-JS$/{r kodza/kodza-hero-screen.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">`.
- Images: the artifact blocks every other host, `kodza.dev` included, without an error. Embed each one as a `data:` URI, with a command if you can run one (`curl -s <url> | base64`; the 1400 px files weigh 10 to 30 KB), never by typing base64 out. If you can't run commands, keep the `<img>` with its `width` and `height`, and tell the user the picture stays blank inside the artifact.
- 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.

### 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 spans the page: a block theme keeps a Custom HTML block to the width of the text column, so put it inside a **Group** block set to **Full width**, with **Inner blocks use content width** turned off.
- 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-hero-screen', $uri . 'kodza-hero-screen.css', [], filemtime($dir . 'kodza-hero-screen.css'));
    wp_enqueue_script('kodza-hero-screen', $uri . 'kodza-hero-screen.js', [], filemtime($dir . 'kodza-hero-screen.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.
- This one spans the page: give the widget its own container, **Content Width: Full Width**, padding 0.
- 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-hero-screen.css` and `assets/kodza-hero-screen.js` (the Files commands with `-o assets/…`).
- In the section: `{{ 'kodza-hero-screen.css' | asset_url | stylesheet_tag }}` and `<script src="{{ 'kodza-hero-screen.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/`): `HeroScreen.tsx` (below), the CSS block under Code saved as `hero-screen.css` and the JS block as `hero-screen.js`, both as they are. The HTML block is already inside the component: skip it.
- Use it: `import { HeroScreen } from '@/components/kodza/HeroScreen';` then `<HeroScreen />`. Props: `vars` (the `--kz-…` variables listed under API, e.g. `vars={{ '--kz-hero-screen-ink': … }}`), `className`, `style` and the other props of its `<section>` (`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 './hero-screen.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 — Hero Screen, for React. From https://kodza.dev/components/hero-screen/
// 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: hero-screen.css and hero-screen.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.

/* Kodza — Hero Screen
   A centred title and its buttons over a screenshot of the product, leaning back in
   perspective. On scroll the scene holds while the screen stands up to face you and grows to its
   real size, passing over the title as it steps back: leaning, the screen sits in shade under a
   long soft shadow; upright, it lights up and the shadow tucks in. Then the page goes on.
   Without the script, or with reduced motion, nothing pins: the title, then the screen, upright.
   Everything is tuned with the --kz-hero-screen-* variables. */
