HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Element name “gcse:searchbox-only” cannot be represented as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “logo” was here.
Errors:
Bad element name “gcse:searchbox-only”: Code point “U+003A” is not allowed
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray doctype.
Stray end tag “span”.
Attribute “pubdate” not allowed on element “time” at this point.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
Duplicate ID “logo”.
End tag “li” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
No “a” element in scope but a “a” end tag seen.
