Consider avoiding viewport values that prevent users from resizing documents.
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “figure” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
