Attribute “alt” not allowed on element “div” at this point.
Stray end tag “param”.
Stray end tag “embed”.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
No space between attributes.
Attribute “pubdate” not allowed on element “time” at this point.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.

Warnings:
