HTML markup errors and warnings
(Rescan now...)
Errors:
Element “figcaption” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Bad value “300px” for attribute “width” on element “iframe”: Expected a digit but saw “p” instead.
Bad value “360px” for attribute “height” on element “iframe”: Expected a digit but saw “p” instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
