✓When to Use

  • Project roadmaps

AI Implementation Prompts

Move from a fast scaffold to production details, then tune timing and edge states.

Create a vertical timeline where the connector line draws down and each milestone card fades in from the left as it becomes active.

Code Example (Tailwind CSS)

A focused implementation sketch you can adapt to your product state.

export function TimelineReveal() {
  const items = ['Brief', 'Prototype', 'Launch'];
  return (
    <div className="relative">
      <div className="absolute left-4 top-0 h-full w-px bg-stone-200" />
      {items.map((item) => <div key={item} className="relative pl-12">{item}</div>)}
    </div>
  );
}
