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.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “main” role is unnecessary for element “main”.
The “contentinfo” role is unnecessary for element “footer”.
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:
CSS: Unknown pseudo-element or pseudo-class “::input-placeholder”.
Attribute “loading” not allowed on element “img” at this point.
Bad value “designer” for attribute “rel” on element “a”: The string “designer” is not a registered keyword.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “aria-controls” attribute must point to an element in the same document.
The “itemprop” attribute was specified, but the element is not a property of any item.
