Check your saved files against the activity brief. Feedback helps you revise; it does not issue a certificate.
Files are read only inside this browser. Keep them in one folder and select index.html together with its CSS and images. After editing, save and select the files again. No submission or progress is stored on a server.

Isolated preview
Links, scripts and external resources are disabled here. Test real navigation in your downloaded page. The preview can scroll horizontally when wider than your screen.
After the automated checks
Do the manual checks in the activity brief: source order, useful wording, keyboard operation and, after module 3, text contrast and 200% zoom. A green result cannot verify your authorship, design quality or full accessibility.
