Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Bad value “./comun/include/conclase.css.php?titulo=Con Clase&color=565d63474e54333a40FD6b00e3e3e35252523d3d3d2121210d0d0dc0c9d29dabb9” for attribute “href” on element “link”: Illegal character in query: space is not allowed.
Malformed byte sequence: “ed”.
Malformed byte sequence: “e1”.
Malformed byte sequence: “fa”.
Malformed byte sequence: “f3”.
Malformed byte sequence: “e9”.
Malformed byte sequence: “f1”.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “con” not allowed on element “a” at this point.
Attribute “clase""” not allowed on element “a” at this point.
Attribute “size” not allowed on element “input” at this point.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “clase""” is not serializable as XML 1.0.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
