HTML markup errors and warnings
(Rescan now...)
Errors:
Element “title” must not be empty.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Warnings:
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.
The “type” attribute is unnecessary for JavaScript resources.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
