  Line 11, Column 41:         document type does not allow element "a" here  …ref="http://www.cloud9comments.com/"><img src="images/glitterplaceholder.gif"           ✉     
                  The element named above was found in a context where it is not allowed.       This could mean that you have incorrectly nested elements -- such as a       "style" element in the "body" section instead of inside "head" -- or       two elements that overlap (which is not allowed).     
            One common cause for this error is the use of XHTML syntax in HTML       documents. Due to HTML's rules of implicitly closed elements, this error       can create cascading effects. For instance, using XHTML's "self-closing"       tags for "meta" and "link" in the "head" section of a HTML document may       cause the parser to infer the end of the "head" section and the       beginning of the "body" section (where "link" and "meta" are not       allowed; hence the reported error).
