(Rescan now...)
Errors:
Bad value “language” for attribute “http-equiv” on element “meta”.
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “50%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Element “gcse:search” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “div”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Element name “gcse:search” cannot be represented as XML 1.0.
This document appears to be written in German. Consider adding “lang="de"” (or variant) to the “html” start tag.
