Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
A “charset” attribute on a “meta” element found after the first 1024 bytes.
Attribute “svgsrc” not allowed on element “img” at this point.
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “id” on element “a”: An ID must not be the empty string.
Duplicate ID “”.
Duplicate attribute “target”.
The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
