An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.

Consider avoiding viewport values that prevent users from resizing documents.
