I built 20 free, open-source HTML pages you can use to reskin existing projects with Claude. No login required.
A developer created 20 free, open-source HTML pages to help reskin existing projects using Claude, noting that while generating functional interfaces is easier, achieving a consistent visual identity still requires iteration. The developer suggests using a prompt to analyze an attached HTML file to extract its visual design system, including typography, colors, spacing, layout principles, components, borders, shadows, and animations, to apply consistently across an existing project while preserving content, functionality, routes, and business logic.

I've been building websites for years, and one thing I've noticed while working with Claude Code is that generating functional interfaces is getting easier, but getting a consistent, distinctive visual identity still takes a lot of iteration.
You can tell Claude to "make it premium" or "make it look like a modern SaaS," but those instructions leave a lot of room for interpretation.
So I've been exploring a different approach:
What if, instead of describing a design to Claude, you gave it an entire working design as a reference?
That's part of the thinking behind a project I recently brought back called InstaLanding.ai .
I built a library of 20 landing pages using plain HTML, CSS, and JavaScript.
Each page is self-contained in a single HTML file. No frameworks, dependencies, or build steps.
Why single-file HTML?
I wanted the designs to be as portable and easy for coding agents to understand as possible.
A single file gives Claude access to the actual implementation:
- Typography, colors, and spacing
- Layout structure and responsive behavior
- Component styling
- Animations and interactions
- The overall visual language
No screenshots to interpret. No dependency trees to navigate. Just working code.
An interesting use case: Reskinning existing Claude Code projects
Say you've already built a dashboard or SaaS application with Claude Code.
The functionality works, but you're not happy with the visual design.
Instead of rebuilding the application, you can give Claude one of these HTML files and ask it to extract and apply the design system.
Here's the prompt I've been exploring:
"Analyze the attached HTML file and extract its visual design system, including typography, colors, spacing, layout principles, components, borders, shadows, and animations. Apply this design language consistently across my existing project. Preserve all existing content, functionality, routes, and business logic. Treat the HTML as the visual source of truth, not as a replacement for my application's architecture."
The goal is to separate two things that often get mixed together during AI-assisted development:
What your application does vs. what your application looks like.
