HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “Layer_1” was here.
The first occurrence of ID “off” was here.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Errors:
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 “target” on element “a”: Browsing context name must be at least one character long.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Duplicate ID “Layer_1”.
Duplicate ID “off”.
The element “main” must not appear as a descendant of the “article” element.
Forbidden code point U+0003.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
End tag “br”.
