HTML markup errors and warnings
(Rescan now...)
Errors:
Duplicate attribute “itemscope”.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “”alternate”” for attribute “rel” on element “link”: The string “”alternate”” is not a registered keyword.
Bad value “”application/rss+xml”” for attribute “type” on element “link”: Expected a token character but saw “”” instead.
Bad value “”http://feeds.feedburner.com/scientopia/fZeU"” for attribute “href” on element “link”: Illegal character in path segment: “"” is not allowed.
Stray end tag “span”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “i”.
Attribute “pubdate” not allowed on element “span” at this point.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “option” without attribute “label” must not be empty.
Attribute “border” not allowed on element “input” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
