HTML markup errors and warnings
(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
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 “src” on element “img”: Must be non-empty.
End tag “span” seen, but there were open elements.
Unclosed element “a”.
No “a” element in scope but a “a” end tag seen.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray doctype.
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 document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
