HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Stray end tag “base”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Saw U+0000 in stream.
Duplicate ID “productGridItem”.
Forbidden code point U+0081.
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The first occurrence of ID “productGridItem” was here.
This document appears to be written in English but the “html” start tag has “lang="sv"”. Consider using “lang="en"” (or variant) instead.
