Compadre.org HTML Check

HTML Validation Tool

Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “schema.DC” for attribute “rel” on element “link”: The string “schema.DC” is not a registered keyword.

The “scheme” attribute on the “meta” element is obsolete. Use only one scheme per field, or make the scheme declaration part of the value.

Element “area” is missing required attribute “alt”.

Bad value “portalLogoMap” for attribute “usemap” on element “img”: A hash-name reference must start with “#”.

The element “img” with the attribute “usemap” must not appear as a descendant of the “a” element.

Stray end tag “h1”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
