Semwebcentral.org HTML Check

HTML Validation Tool

Errors

Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)

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.

Bad value “en ” for attribute “lang” on element “html”: The language subtag “en ” is not a valid language subtag.

Text not allowed in element “select” in this context.

Stray doctype.

Stray start tag “html”.

Stray start tag “head”.

Attribute “http-equiv” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.

Element “title” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

Attribute “name” not allowed on element “meta” at this point.

A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

Stray end tag “head”.

Start tag “body” seen but an element of the same type was already open.

Duplicate ID “page”.

Duplicate ID “searchform”.

Duplicate ID “s”.

End tag for “body” seen, but there were unclosed elements.

Unclosed element “div”.

Warnings

The first occurrence of ID “page” was here.

The first occurrence of ID “searchform” was here.

The first occurrence of ID “s” was here.

This document appears to be written in English but the “html” start tag has “lang="en "”. Consider using “lang="en"” (or variant) instead.
