Errors:
Bad start tag in “img” in “head”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Element “title” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Duplicate attribute “id”.
Bad value “tabpanel” for attribute “role” on element “li”.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

Potentially bad value “allow-same-origin allow-scripts allow-popups allow-forms” for attribute “sandbox” on element “iframe”: Setting both “allow-scripts” and “allow-same-origin” is not recommended, because it effectively enables an embedded page to break out of all sandboxing.
