Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
The first occurrence of ID “language-switch-dropdown” was here.
This document appears to be written in Dutch. Consider adding “lang="nl"” (or variant) to the “html” start tag.
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “img” is missing required attribute “src”.
Element “picture” not allowed as child of element “picture” in this context. (Suppressing further errors from this subtree.)
Element “picture” is missing a required instance of child element “img”.
Bad value “tel:+31 (0)412 66 80 11” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “language-switch-dropdown”.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Element “style” not allowed as child of element “noscript” in this context. (Suppressing further errors from this subtree.)
