Errors:
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete.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The “profile” attribute on the “head” element is obsolete.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 numeric character reference expanded to carriage return.
No “p” element in scope but a “p” end tag seen.
The element “input” must not appear as a descendant of the “button” element.
Attribute “href” not allowed on element “span” at this point.
Duplicate ID “user-login-form”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
