HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Attribute “type” not allowed on element “img” 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.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value ““text/javascript"” for attribute “type” on element “script”: Expected a token character but saw ““” instead.
