(Rescan now...)
Errors:
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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “HorizontalBar”.
Bad value “” for attribute “id” on element “span”: An ID must not be the empty string.
Bad value “” for attribute “name” on element “textarea”: Must not be empty.
The element “a” must not appear as a descendant of the “button” element.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Warnings:
