Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “a” instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad value “” for attribute “id” on element “body”: An ID must not be the empty string.
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.
End tag “br”.
Bad value “0” for attribute “rel” on element “a”: The string “0” is not a registered keyword.
Bad value “1” for attribute “rel” on element “a”: The string “1” is not a registered keyword.
Start tag “a” seen but an element of the same type was already open.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
