HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “hgroup” in this context. (Suppressing further errors from this subtree.)
Bad value “article” for attribute “rel” on element “a”: The string “article” is not a registered keyword.
The “rev” attribute on the “a” element is obsolete. Use the “rel” attribute instead, with a term having the opposite meaning.
Bad value “true” for attribute “async” on element “script”.
Start tag “a” seen but an element of the same type was already open.
Bad value “video” for attribute “rel” on element “a”: The string “video” 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:
Empty heading.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
