Errors:
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “application/xhtml+xml; charset=utf-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
No space between attributes.
A slash was not immediately followed by “>”.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Bad value “” for attribute “itemtype” on element “body”.
Attribute “http:” not allowed on element “body” at this point.
Attribute “www.schema.org” not allowed on element “body” at this point.
Attribute “webpage""” not allowed on element “body” at this point.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate attribute “id”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Attribute “http:” is not serializable as XML 1.0.
Attribute “webpage""” is not serializable as XML 1.0.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
