The prompt

Build an onboarding stepper with Tailwind CSS: a horizontal row of numbered step circles connected by lines, with completed steps filled dark, the current step ringed, and future steps muted. Below, a card with the current step title, a short description, and Back/Continue buttons. Then add JavaScript that actually walks the flow: hold the step copy in an array, repaint the circles and connector lines as done / current / upcoming when the index moves, swap the title and description, disable Back on the first step, and turn Continue into Finish on the last one before showing a completed state.

Paste it into Claude, Cursor, v0 or any AI coding tool. Prefer the finished markup? Open the Tailwind source.
