HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Document uses the Unicode Private Use Area(s), which should not be used in publicly exchanged documents. (Charmod C073)
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
Element “img” is missing required attribute “src”.
No “p” element in scope but a “p” 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.
