HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
Empty heading.
The first occurrence of ID “btn-small-screen” was here.
Errors:
Duplicate ID “btn-small-screen”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “webkitallowfullscreen” not allowed on element “iframe” at this point.
Attribute “mozallowfullscreen” not allowed on element “iframe” at this point.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
