HTML markup errors and warnings
(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “name” not allowed on element “div” at this point.
Element “figcaption” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Stray end tag “div”.
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The “frameborder” attribute on the “iframe” element is obsolete.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.
The “aria-labelledby” attribute must point to an element in the same document.
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).
