HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete.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 “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “span” at this point.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The element “h4” must not appear as a descendant of the “dt” element.
Warnings:
Attribute “"” is not serializable as XML 1.0.
