Errors

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

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

Duplicate ID “web_login”.

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

Attribute “rel” not allowed on element “li” at this point.

No “p” element in scope but a “p” end tag seen.

No space between attributes.

Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.

A slash was not immediately followed by “>”.

End tag had attributes.

The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.

The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

End tag for “body” seen, but there were unclosed elements.

Unclosed element “div”.

Warnings

Consider avoiding viewport values that prevent users from resizing documents.

The first occurrence of ID “web_login” was here.

The value of attribute “style” on element “div” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.

The value of attribute “src” on element “img” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
