HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The first occurrence of ID “navbarDropdown” was here.
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
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).
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
Duplicate ID “navbarDropdown”.
The “center” element is obsolete. Use CSS instead.
Stray end tag “div”.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “div” not allowed as child of element “h4” in this context. (Suppressing further errors from this subtree.)
End tag “footer” seen, but there were open elements.
Unclosed element “div”.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “main”.
