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”.
Attribute “blzsys” not allowed on element “script” at this point.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
The element “header” must not appear as a descendant of the “header” element.
Element “div” not allowed as child of element “label” in this context. (Suppressing further errors from this subtree.)
Element “source” is missing required attribute “srcset”.
Element “img” is missing required attribute “src”.
Element “a” not allowed as child of element “hgroup” in this context. (Suppressing further errors from this subtree.)
Element “hgroup” is missing a required instance of one or more of the following child elements: “h1”, “h2”, “h3”, “h4”, “h5”, “h6”.
Element “div” not allowed as child of element “hgroup” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
