HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
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.
Attribute “src” not allowed on element “link” at this point.
Bad value “_blanck” for attribute “target” on element “a”: Reserved keyword “blanck” used.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
The “center” element is obsolete. Use CSS instead.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “center”.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
