HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “” for attribute “href” on element “link”: Must be non-empty.
Attribute “href” not allowed on element “button” at this point.
Element “img” is missing required attribute “src”.
End tag “h2” seen, but there were open elements.
Unclosed element “a”.
No “a” element in scope but a “a” end tag seen.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “source”.
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
Attribute “height” not allowed on element “a” at this point.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
