HTML markup errors and warnings
(Rescan now...)
Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “/de/node/10/seniorenresidenz-finden?type[]=109&type[]=110” for attribute “href” on element “a”: Illegal character in query: “[” is not allowed.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Bad value “/de/angebot/seniorenresidenz-finden?type[]=109&type[]=110” for attribute “href” on element “a”: Illegal character in query: “[” 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.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
