Scroll this window — the demo is further down, like a real page.

Fade up

Animate me on scroll

Same class and keyframes as the copied CSS.

End of mock page.

Export

Intersection Observer adds .is-inview. Reduced-motion rules are in the CSS.

/* Scroll reveal — Intersection Observer adds .is-inview when the element enters the viewport.
   Pair with the JavaScript snippet. Respects prefers-reduced-motion. */

@keyframes jn-scroll-fadeUp {
  from {
    opacity: 0;
    transform: translateY(2.5rem);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

.jn-scroll {
  opacity: 0;
}

.jn-scroll.is-inview {
  animation: jn-scroll-fadeUp 0.6s ease-out 0s both;
}

@media (prefers-reduced-motion: reduce) {
  .jn-scroll,
  .jn-scroll.is-inview {
    animation: none !important;
    opacity: 1 !important;
    transform: none !important;
  }
}

Scroll reveals you can paste, not a motion library

Most “animate on scroll” tools lock you into React or a 30kb package. Reveals write CSS @keyframes plus Intersection Observer. Scenes pin headlines, pan galleries, stack cards, draw paths, or count up — copy HTML/CSS (and JS only if needed), or an AI prompt. For keyframes that are not tied to scroll, use the CSS Animation Builder. For the CSS-only animation-timeline: view() path, see the Pure CSS scroll animations guide.

Mini-browser preview

A real scroll window with a URL bar and a visible scrollbar — not a static box.

Copy CSS, JS, HTML, or an AI prompt

One export panel, one copy button, plus a Cursor/Claude prompt for that preset.

Reveals and scenes

Fade, slide, and stagger — plus parallax, stacked cards, path draw, count-up, and more.

Private

100% client-side. Animation settings never leave this tab.

How to use the scroll animation generator

  1. 1

    Pick a preset

    Switch Reveals or Scenes, then choose a chip. Each chip has a tiny motion hint.

  2. 2

    Scroll the preview

    Use the mini-browser. Jump to demo scrolls inside that window. Replay resets to the top.

  3. 3

    Tune reveals if you need to

    Duration, delay, easing, and threshold sit under the reveal chips. Scenes play from scroll.

  4. 4

    Copy the active tab

    CSS, JS, HTML, or an AI prompt — one primary Copy button.

Frequently asked questions

How does this scroll animation generator work?

Pick a reveal (fade, slide, scale, stagger) or a scene (sticky headline, parallax, stacked cards, and more). Reveals write CSS @keyframes plus Intersection Observer. Scenes write a pinned or scroll-linked section — HTML and CSS, plus JS only when needed.

What is the AI prompt for?

The AI prompt tab is a self-contained brief for that exact preset: behavior, HTML, CSS, and JS. Paste it into Cursor or Claude. No Jaconir branding — restyle copy and colors to your project.

What kinds of scenes are included?

Sticky headline, scale then scroll, parallax layers, horizontal gallery, stacked cards, clip-path reveal, split text, progress bar, SVG path draw, number count-up, and Ken Burns image zoom. Each has a live preview and copy-paste output.

Why Intersection Observer instead of animation-timeline: view()?

Reveals use Intersection Observer so they work in every modern browser, including Safari. Scenes use sticky positioning and scroll-linked CSS variables. The AI prompt allows animation-timeline if you keep a fallback.

How do I add the CSS and JavaScript to my site?

Copy HTML into the page, CSS into your stylesheet, and JS before </body> when the snippet is not a “CSS only” comment. Or paste the AI prompt into an agent.

Does this respect prefers-reduced-motion?

Yes. Generated CSS includes a reduced-motion media query. Reveal scripts skip the observer and show the final state. Scene scripts skip scroll-linking so the layout stays readable.

Does this tool upload my code?

No. Presets, preview, and export run in your browser. Nothing is sent to a server, and there is no account.
