About the preview

  • The preview is a fully sandboxed frame: HTML and CSS render, but JavaScript, forms and pop-ups are blocked, so pasted snippets can't run code.
  • Switch between Mobile (375px), Tablet (768px) and Desktop to test media queries — device sizes scale down to fit your screen.
  • Download saves a single index.html with your CSS inlined.
