HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “Imagetoolbar” for attribute “http-equiv” on element “meta”.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
Attribute “xmlns:av” not allowed here.
The “shape” attribute on the “a” element is obsolete. Use “area” instead of “a” for image maps.
Duplicate attribute “title”.
Element “nobr” not allowed as child of element “label” 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 “action” on element “form”: Must be non-empty.
No space between attributes.
Stray end tag “div”.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
Attribute with the local name “xmlns:av” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
