Frequently asked questions about the Scroll Progress Bar (Top of Page)
How do I add a Scroll Progress Bar (Top of Page) to my website?+
Copy the source code from the "Copy code" button above and save it as a .tsx file in your components folder. The Scroll Progress Bar (Top of Page) is built with React and Tailwind CSS — add those as dependencies if they are not already in your project. Import and render the component wherever you need it. Every prop is optional and typed.
Can I use the Scroll Progress Bar (Top of Page) with Claude Code, Cursor, or Lovable?+
Yes. Each prompt tab above is tuned specifically for Claude Code, Cursor, Codex, Lovable, Replit, and Google Stitch. Paste the prompt into whichever AI coding tool you are using and it will generate a Scroll Progress Bar (Top of Page) matched to your existing file structure, design tokens, and brand color. Claude Code and Cursor work best when your project is already open — they slot the component directly into your codebase. Lovable and Replit are fastest for a standalone preview.
How do I customise the progress-bar design and colors?+
The Scroll Progress Bar (Top of Page) uses Tailwind utility classes throughout, so every color, spacing value, and font weight is one class away from changing. Replace any color class with your brand token (for example, swap `bg-black` for `bg-[#your-hex]`). To change the animation timing, update the `duration-` or `delay-` classes, or pass new values into the Framer Motion `transition` prop if the component uses it. For a full brand restyle, paste the component into Claude Code or Cursor and describe your design system.

Does the Scroll Progress Bar (Top of Page) work with TypeScript?+
