HTML markup errors and warnings
(Rescan now...)
Warnings:
Potentially bad value “in-ID” for attribute “hreflang” on element “link”: The language subtag “in” is deprecated. Use “id” instead.
The “type” attribute for the “style” element is not needed and should be omitted.
Module scripts are not supported in most browsers yet.
Text run is not in Unicode Normalization Form C.
The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
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:
Element “track” is missing required attribute “src”.
The element “button” must not appear as a descendant of the “a” element.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
CSS: “background-color”: “undefined” is not a “background-color” value.
Attribute “loading” not allowed on element “img” at this point.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “body” 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”.
