HTML markup errors and warnings
(Rescan now...)
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “banner” role is unnecessary for element “header”.
The “main” role is unnecessary for element “main”.
The “complementary” role is unnecessary for element “aside”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate attribute “href”.
The “itemprop” attribute was specified, but the element is not a property of any item.
