HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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.
Attribute “"” is not serializable as XML 1.0.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
Errors:
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No “li” element in scope but a “li” end tag seen.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “_block” for attribute “target” on element “a”: Reserved keyword “block” used.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “script” at this point.
