HTML markup errors and warnings
(Rescan now...)
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.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.
Bad value “” for attribute “height” on element “img”: The empty string is not a valid non-negative integer.
Bad value “.v2-pagetopTarget” for attribute “rel” on element “a”: The string “.v2-pagetopTarget” is not a registered keyword.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
