Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “image/gfx/favicon/png” for attribute “type” on element “link”: Expected a token character, whitespace or a semicolon but saw “/” instead.
Bad value “” for attribute “srcset” on element “img”: Must contain one or more image candidate strings.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “v” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
Element “img” is missing required attribute “src”.
The “sizes” attribute may be specified only if the “srcset” attribute is also present.
Bad value “” for attribute “src” on element “iframe”: Must be non-empty.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Attribute “xmlns” is not serializable as XML 1.0.
