Powerlibrary.org HTML Check

HTML Validation Tool

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The “profile” attribute on the “head” element is obsolete.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.

Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

Duplicate attribute “class”.

Stray end tag “head”.

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

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

A slash was not immediately followed by “>”.

Stray end tag “div”.

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.
