Wenas como dice el titulo estoy tratando de validar con la w3.org
bueno parece estar casi todo bien...
Les dejo los errores que me marca pero no los entiendo.
Validation Output: 4 Errors -
Line 13, Column 31: document type does not allow element "script" here; assuming missing "body" start-tag <script type="text/javascript"> ✉ - Line 18, Column 6: document type does not allow element "body" here <body> ✉
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). - Line 43, Column 50: an attribute value must be a literal unless it contains only name characters … <div class="noticias_cont"><img src=/imagenes/comillas.png alt='imagen' /></… ✉
You have used a character that is not considered a "name character" in an attribute value. Which characters are considered "name characters" varies between the different document types, but a good rule of thumb is that unless the value contains only lower or upper case letters in the range a-z you must put quotation marks around the value. In fact, unless you have extreme file size requirements it is a very very good idea to always put quote marks around your attribute values. It is never wrong to do so, and very often it is absolutely necessary. - Line 63, Column 7: end tag for "body" omitted, but OMITTAG NO was specified </html> ✉
You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">". -
