HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Errors:
End tag “nav” seen, but there were open elements.
Unclosed element “ul”.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The text content of element “script” was not in the required format: Content contains the character sequence “<!--” without a later occurrence of the character sequence “-->”.
Attribute “language” not allowed on element “form” at this point.
End tag “div” seen, but there were open elements.
Unclosed element “section”.
