(Rescan now...)
Errors:
Attribute “http-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Text not allowed in element “iframe” in this context.
No “p” element in scope but a “p” end tag seen.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Bad value “” for attribute “name” on element “input”: Must not be empty.
Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “footer_menu”.
Warnings:
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The “border” attribute is obsolete.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 “form” role is unnecessary for element “form”.
