A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad value “true” for attribute “async” on element “script”.
Element “h2” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
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.
Bad value “dofollow” for attribute “rel” on element “a”: The string “dofollow” is not a registered keyword.
No “p” element in scope but a “p” end tag seen.
Bad character “ ” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
