HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “searchgo” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “"” is not serializable as XML 1.0.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Errors:
Attribute “property” not allowed on element “meta” at this point.
Attribute “name” not allowed on element “meta” at this point.
Duplicate ID “searchgo”.
Attribute “webkitallowfullscreen” not allowed on element “iframe” at this point.
Attribute “mozallowfullscreen” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “a” at this point.
