Headless UI fonts and type scale
Headless UI's website sets both headings and body text in Inter var, with ui-monospace for code. Body text is 14px, section headings 20px and the largest display type 48px, at weight 600. If you can't use Inter var, ask your AI for the closest free match and keep the sizes and weights.

How do I build a site that looks like Headless UI with AI?
Open the Prompt tab above, change its first line to what you are building, and paste it into Lovable, v0, Bolt, Claude Code or Cursor. For a whole project, install the Claude skill or the Cursor rule instead, so every screen keeps the style. Build something original: keep Headless UI's look, not its name, logo or copy.
