HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Attribute “"data-next” is not serializable as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"data-next” not allowed on element “th” at this point.
Element “img” is missing required attribute “src”.
