Open the editor01
Start with index.html
Find index.html at the ZIP root. If it references ./style.css, keep that stylesheet beside the HTML file.
02
Match references to files
For href="./style.css", include style.css beside the HTML. For src="./assets/photo.jpg", include photo.jpg in assets. Names and letter case must match.
03
Remove computer file addresses
file:///..., C:\... and /Users/... do not refer to files on the published site. Replace them with relative paths and include the files. Check external HTTPS resources separately.
04
Upload and check again
Save the corrected copy, package it without an extra parent folder and upload. Inspect the published page and browser network errors. For a 404, compare paths; for a blocked resource, check the protocol and source settings.
