Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “div” seen, but there were open elements.
Unclosed element “button”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

The “for” attribute of the “label” element must refer to a non-hidden form control.
