HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “schema.dc” for attribute “rel” on element “link”: The string “schema.dc” is not a registered keyword.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “reply-to” for attribute “http-equiv” on element “meta”.
Element “ul” not allowed as child of element “span” 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.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Element “img” is missing required attribute “src”.
Bad value “150px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
The “aria-labelledby” attribute must point to an element in the same document.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Empty heading.
