Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “button” role is unnecessary for element “button”.
The value of attribute “src” on element “img” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
Attribute “<” is not serializable as XML 1.0.
Errors:
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “header” seen, but there were open elements.
Unclosed element “div”.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
