Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “youtube-field-player--2” was here.
Attribute “aria-required” is unnecessary for elements that have attribute “required”.
The “main” role is unnecessary for element “main”.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Element “div” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “00Z” for attribute “datetime” on element “time”: The literal did not satisfy the time-datetime format.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Text not allowed in element “iframe” in this context.
Duplicate ID “youtube-field-player--2”.
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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
