The prompt

Build a floating pill navigation with Tailwind CSS: a fixed, centered, fully rounded bar that hovers a few pixels below the top of the viewport with a translucent white background, backdrop blur, a hairline border, and a soft shadow. Inside, a compact logo mark, a divider, three or four links with rounded hover backgrounds and one active link with a filled pill, then a small dark CTA button at the end. Keep the whole bar to a width that hugs its content and hide the middle links below md.

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