Errors:
Legacy encoding “euc-jp” used. Documents must use UTF-8.
Bad value “text/html; charset=EUC-JP” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Element “link” is missing one or more of the following attributes: “itemprop”, “property”, “rel”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Element “dl” is missing a required instance of child element “dd”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
