Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “GER” for attribute “hreflang” on element “link”: The language subtag “ger” is not a valid ISO language part of a language tag.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
The element “button” must not appear as a descendant of the “a” element.
No space between attributes.
Element “p” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
CSS: “background-color”: Parse Error.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Attribute “;” not allowed on element “span” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “form” in this context. (Suppressing further errors from this subtree.)
The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The “charset” attribute on the “script” element is obsolete.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “main” role is unnecessary for element “main”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “;” is not serializable as XML 1.0.
The “contentinfo” role is unnecessary for element “footer”.
