The “version” attribute on the “html” element is obsolete. You can safely omit it.

The “profile” attribute on the “head” element is obsolete.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

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

No space between attributes.

Element “input” is missing required attribute “alt”.

End tag “td” seen, but there were open elements.

Unclosed element “div”.

Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
