HTML markup errors and warnings
(Rescan now...)
Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
CSS: Parse Error.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “type” attribute for the “style” element is not needed and should be omitted.
