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.htmlwith your CSS inlined.
