Errors:
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “hr” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “main” in this context. (Suppressing further errors from this subtree.)
Attribute “alt” not allowed on element “a” at this point.
The element “img” with the attribute “usemap” must not appear as a descendant of the “a” element.
Element “icon” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
The hash-name reference in attribute “usemap” referred to “largeImage”, but there is no “map” element with a “name” attribute with that value.
The hash-name reference in attribute “usemap” referred to “smallImage”, but there is no “map” element with a “name” attribute with that value.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
