Warnings:

Consider avoiding viewport values that prevent users from resizing documents.

The “navigation” role is unnecessary for element “nav”.

Empty heading.

Errors:

Bad value “screen, presentation” for attribute “media” on element “link”: Expected a CSS media type but the query ended.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The “big” element is obsolete. Use CSS instead.
