HTML markup errors and warnings
(Rescan now...)
Errors:
The “text” attribute on the “body” element is obsolete. Use CSS instead.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Stray end tag “span”.
Duplicate attribute “class”.
Duplicate attribute “style”.
The element “label” must not appear as a descendant of the “a” element.
Element “h4” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “p” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “div”.
Warnings:
