HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Element “p” not allowed as child of element “a” 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.)
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “section”.
Warnings:
The “complementary” role is unnecessary for element “aside”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
