How to Make an Animated Website With AI: A Step-by-Step Guide

Disclosure: ScrollHaus publishes this guide and is one of the resources it mentions. Tools are described from their public pages, read on October 5, 2026.

What is an animated website?

An animated website uses motion to guide attention: elements that reveal as you scroll, backgrounds that move, headlines that assemble, and sections that respond to the pointer. Done well, motion explains the page. Done badly, it slows it down. The goal is a small number of deliberate effects, not constant movement.

The seven steps at a glance

1. Choose one visual direction and look at it moving.
2. Decide what you need: a prompt, components, or a complete page.
3. Pick the AI builder.
4. Write a specific first prompt.
5. Add motion in layers: reveals, background, scroll story.
6. Test on a phone.
7. Publish and measure.

Step 1: choose one direction and watch it move

Screenshots hide motion. Before you write a prompt, open a few live previews and scroll them slowly. Note the pacing, what moves, and what stays still. You can browse live previews on ScrollHaus, and prompt libraries such as MotionSites and GetLayers publish previews of their designs too. Pick one direction, because mixing three styles produces a page with no identity.

Step 2: decide what you need

• A prompt when you want an AI builder to generate the page. MotionSites and GetLayers sell prompts for this, and our guide to free prompts lists free options.
• Components when you are building an app and need animated pieces. Magic UI, Aceternity UI, React Bits and 21st.dev all supply them, compared in our component library comparison.
• A complete page with source when you want the motion to behave exactly as previewed. That is what ScrollHaus provides.

Step 3: pick the AI builder

Step 4: write a specific first prompt

A good first prompt names the audience, the sections, the type, the colours, and the motion rules. Replace the brackets:

Build a single-page website for [brand], which sells [offer] to [audience].
Sections: hero, three benefits, a pinned horizontal gallery, pricing, FAQ, footer.
Style: [two colours], [one display typeface and one body typeface], generous spacing.
Motion: headline words rise one by one on load; sections fade up once on scroll;
ease-out curves, 600 to 900 ms; respect prefers-reduced-motion.
Mobile first. One HTML file, no build step, images in an assets folder.

If you start from a reference page, say so: "keep the scroll timing and structure of this page; only change the copy and images." That sentence protects the motion from being reinvented. Our guide to using AI website prompts in Lovable, Bolt and Claude Code goes deeper.

Step 5: add motion in layers

1. Reveals: text and images ease in once, as they enter the screen.
2. Background: one moving element behind the hero, such as a video loop or a canvas effect.
3. Scroll story: tie one signature moment to scroll position, such as a pinned section or a film that scrubs with the wheel.

Add one layer at a time and check the result before the next. For more patterns see website animations and scroll animation websites.

Step 6: test on a phone

• Scroll the whole page on a real phone, not a resized window.
• Check for dropped frames when large media loads.
• Turn on reduced-motion in your system settings and confirm the page still works.
• Check that text stays readable over moving backgrounds.

Step 7: publish and measure

Publish to any static host, then watch real usage: how far people scroll, where they leave, and how fast the page loads. Use that, not taste alone, to decide which animations stay.

Which tools make which kind of animation?

You can build animated websites with very different tools, and it helps to match the tool to the effect:

• CSS and JavaScript: reveals, hover effects and simple scroll triggers need no library at all. A web developer or an AI builder can write them in a few lines.
• GSAP and similar scroll libraries: pinned sections, scrubbed timelines and complex sequences.
• Three.js: real 3D scenes and objects that respond to the pointer or scroll. It is powerful but heavier, so use it for one signature scene.
• Video and frame sequences: cinematic backgrounds and scroll-driven films, as long as the media is compressed and loaded in stages.

If the site is for marketing, such as a product launch or a portfolio, keep the number of effects small and put the strongest one near the top. If you want a tutorial to follow along with, a good video walkthrough of an AI builder plus a live reference page is usually faster than reading documentation. You can also make animated websites from a reference page: open its preview, note which effects it uses, and tell your builder to build exactly those, with your logo, colours, email capture form and social links in place of the original.

How much does it cost?

You can start free. Claude Code, Cursor, Lovable, Bolt and v0 all have limited free or low-cost tiers at the time of writing, and free references exist: GetLayers lists a free plan of curated layers with full prompts, and ScrollHaus offers selected free-to-build websites and a free GitHub repository. Paid libraries start from about $49 for a MotionSites prompt pack or $49.99 every three months for ScrollHaus.

Common mistakes

• Starting from a blank prompt and asking for "something stunning".
• Animating everything, so nothing stands out.
• Using heavy video without compressing it.
• Letting the AI builder split a document-level scroll engine into components.
• Skipping the phone test.
