Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
Bad value “_none” for attribute “target” on element “a”: Reserved keyword “none” used.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
End tag “div” seen, but there were open elements.
Unclosed element “form”.
Stray end tag “form”.
Bad value “_home” for attribute “target” on element “a”: Reserved keyword “home” used.
Attribute “alt” not allowed on element “a” at this point.
Stray end tag “a”.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Bad value “135px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
