How to use the HTML editor

  1. Edit the sample markup in the HTML panel.
  2. Select Run code to refresh the preview.
  3. Change one element at a time and compare the rendered result.

This tool is useful for testing page structure, headings, links and simple HTML components. The preview is isolated and disables scripts. Copy code you want to keep into your own project; this page does not save an editor session.

When the preview does not change

Select Run code after editing. Check that tags are closed and that the markup is placed in the HTML panel.
