Bad value “expires” for attribute “http-equiv” on element “meta”.

Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “button” at this point.
The element “button” must not appear as a descendant of the “a” element.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “product_div”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Warnings:
Attribute “"” is not serializable as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
