Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “Description” for attribute “http-equiv” on element “meta”.
Bad value “img1” for attribute “rel” on element “a”: The string “img1” is not a registered keyword.
Bad value “img2” for attribute “rel” on element “a”: The string “img2” is not a registered keyword.
Bad value “img3” for attribute “rel” on element “a”: The string “img3” is not a registered keyword.
Bad value “img4” for attribute “rel” on element “a”: The string “img4” is not a registered keyword.
Bad value “img5” for attribute “rel” on element “a”: The string “img5” is not a registered keyword.
Bad value “map” for attribute “rel” on element “a”: The string “map” is not a registered keyword.
No space between attributes.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
