How to Build Animated Websites With Claude Design and Seedance 2.0
The fastest way to build an animated hero website right now is a four-tool pipeline: Nano Banana Pro for the still image, Claude Design for the website mockup and tweaks, Seedance 2.0 for the background video, and Claude Code for final polish and deploy. I built one site this way for a fictional SaaS called Olympus, end-to-end, in about an hour. Here's the full workflow with every prompt and tradeoff that matters.
Why This Stack?
Each tool earns its slot:
- Nano Banana Pro — best-in-class AI image model for hero compositions
- Claude Design — Anthropic's design tool, dominates fast iteration via tweaks and macro variants
- Seedance 2.0 — current top video model, produces subtle, cinematic motion
- Claude Code — the universal terminal harness for final code edits and deploy
I run all of these through Higgsfield, which connects to all the major AI content models through a single MCP server. You can run them through their native interfaces too — the workflow is the same.
Step 1: Plan the Hero Composition Before You Generate Anything
The biggest mistake people make with AI image generation is prompting before they know what the page actually looks like.
Decide where the dead space is going to be first. Where will the hero text live — left, right, center, top? Where do the buttons go? Is there a banner or a ticker on the bottom? Whatever the composition is, that dictates your prompt to Nano Banana Pro.
If you don't know what your options are, the fastest research move is to scroll Dribbble for "landing page SaaS" or whatever niche you're in. Save 3-5 reference compositions before you write a single prompt. You only need 2-3 ideas in your back pocket — but you need them before you generate.
For my Olympus site (a fictional market intelligence platform), I picked a half-and-half composition: hero image on the right, hero copy plus buttons on the left, a top banner with nav, and a ticker on the bottom. I prompted Nano Banana Pro with that composition explicitly.
Lean on Claude or Claude Code to write the actual image prompt. Don't try to wing the prompt yourself — Nano Banana Pro responds dramatically better to structured prompts that name composition, lighting, mood, and subject in the right order.
Step 2: Bring the Image Into Claude Design
In Claude Design, go to the left panel → Prototype → name your project → pick High Fidelity → Create.
Once you're in the project, the first move is to add context. Drop in the still image you generated. If you have additional reference shots from Dribbble, add those too. More reference equals better first pass.
Then write your design prompt. Again — let Claude Code write it for you. The Olympus prompt I used had:
- Company description
- Detailed hero specifications
- Section list for the landing page
- Motion notes
- The single most important line: "Ask me any questions before you begin."
That last line is the unlock. Claude Design has a plan-mode feature like Claude Code — it'll come back with a Q&A before generating anything. Even if your prompt is mediocre, the Q&A drags you into a robust first pass.
For Olympus, the questions covered typography, color palette, copy voice, hero composition, section order, and tweak preferences. Always pick as many tweaks as possible at this stage — you can prune later, but you can't add them retroactively without starting over.
Watch the usage
Claude Design has its own usage tier separate from your Claude Pro / Max plan. Even on the $200/month Max 20x plan, you get the same Claude Design usage as a Pro user, which is brutal. My Olympus build cost about $5 in extra Claude Design usage. Keep an eye on the meter — a single design system call can eat 30% of your weekly Claude Design usage.
Step 3: Macro Variants Before Tweaks
When the first pass renders, do not start tweaking immediately. Run the variant move first.
Prompt Claude Design: "Create two additional layout variants for our web page that I can click through. Suggest some new designs we could include."
This is the same variant trick that pays off in every design tool I use. You're not iterating on a single layout — you're forcing the tool to show you 2-3 macro directions you'd never have thought to ask for.
For Olympus, the original was a cinematic full-bleed hero. Claude Design came back with two more — an archive variant and a terminal variant. The terminal one was unexpectedly cool. This is the actual unlock of Claude Design over Claude Code: rapid macro-variant iteration is built into the tool.
You'll spend 10 seconds picking your favorite. That 10 seconds saves you an hour of trying to prompt your way into a layout direction.
Step 4: Aggressive Tweaks on the Winning Variant
Once you've picked the variant, prompt Claude Design: "Let's stick with the cinematic. Remove the other two. Aggressively increase the number of tweaks available."
You'll go from ~5 tweaks (theme, accent, headline, logo, motion) to ~15 (font, body font, mono font, type scale, CTA copy, overlay darkness, ember glow, and more). Now you can rip through every visual decision in minutes instead of sending one prompt per change.
This is where Claude Design earns its slot in the stack. The tweak panel is the fastest visual iteration loop I've used in any AI design tool.
Step 5: Generate the Background Video With Seedance 2.0
Once the static design is at ~90% of where you want it, animate the hero image.
In Seedance 2.0:
- Drag the still image in as the starting frame
- Write a deliberately subtle prompt
- Set 16:9, 1080p minimum, 15 seconds
My Olympus prompt: "Keep the motion extremely slow, clouds barely moving, embers from the fire, and his hands slowly drifting."
Three rules for hero background video:
- Subtle wins. You don't want it to look like a video game cutscene. The hero is supporting your copy, not stealing focus.
- 15 seconds is the right length. Long enough that most visitors don't catch the loop point before they scroll. Short enough that mobile bandwidth doesn't tank.
- Don't use the model's "enhance my prompt" feature. Always keep manual control of the prompt. The "enhanced" version usually loses your structural intent.
Expect 4-5 generations to get one usable take. That's normal. Seedance is good but not deterministic.
When you have one you like, download the MP4.
Mobile note
Don't ship the video on mobile. Most modern Claude Design exports automatically fall back to the still image for smaller viewports — but verify it's doing that before deploy. Background video on mobile = abandoned page.
Step 6: Drop the Video Into Claude Design
Back in Claude Design, drop the MP4 into the prompt window. Then prompt: "Can we swap the still image for the video I just uploaded for the hero background?"
That's it. Claude Design swaps the asset and re-renders the hero with motion.
At this point you're done with Claude Design. Time to move to Claude Code where usage isn't a cliff.
Step 7: Hand Off to Claude Code
In Claude Design, click Share → Hand off to Claude Code. Because the project includes an MP4, the copy command sometimes fails to bundle the video. The reliable path is Download Zip instead.
Extract the zip. Drop the folder into Claude Code with a prompt like: "Extract all these files for the web page we're building, then spin up a dev server."
Claude Code will mount the project, install whatever's needed, and run a local dev server. You're now in normal Claude Code territory — make whatever final tweaks you need, push to GitHub, deploy through Vercel or Netlify.
This is the workflow's biggest insight: Claude Design for the design decisions, Claude Code for everything that comes after. Don't try to run the whole build inside Claude Design. The usage will kill you and the terminal handoff is too easy to skip.
What Else Can You Use Instead of Seedance?
Three real alternatives in 2026:
- Kling 3.0 — Solid. A tier. Slightly less cinematic than Seedance but cheaper.
- Veo 3.1 — Getting outdated and expensive. B tier.
- Seedance 2.0 — Current best for hero-quality animation. The default.
Unless you have a specific reason to switch, use Seedance.
Frequently Asked Questions
Do I need Higgsfield to do this workflow?
No. You can use Nano Banana Pro and Seedance 2.0 directly through their native interfaces or any MCP server that exposes them. Higgsfield is convenient because it puts all the major content models behind a single connector — but the workflow is the same regardless of which interface you use.
Why use Claude Design instead of just Claude Code for the design step?
Speed of macro variation. Asking for three completely different layouts and getting them rendered side by side takes 10 seconds in Claude Design and would be a much longer back-and-forth in Claude Code. Once the layout direction is locked, Claude Code is faster for everything else — but the macro-variant loop is where Claude Design pulls ahead.
How long should the hero background video be?
15 seconds is the sweet spot. Long enough that most visitors won't catch the loop point before scrolling. Short enough that the file size doesn't tank page load. Don't try to make it a perfect loop — usable 15-second clips are easier to generate than perfect 8-second loops.
What's the total cost of this workflow?
Roughly $5 of extra Claude Design usage (if you blow through your normal allotment), plus whatever Higgsfield credits you spend on image and video generation. Realistically $10-20 for a full build if you do reasonable iteration. Compare that to a contracted designer build at $500-2,000 per hero and the math gets obvious quickly.
Will the hero video play on mobile?
By default, modern Claude Design exports detect viewport size and fall back to the still image on mobile. Verify that's happening before you deploy — background video on mobile is a page-abandonment mistake.
