Stray end tag “input”.

Attribute “value” not allowed on element “input” at this point.

Duplicate ID “q”.

Element “img” is missing required attribute “src”.

Duplicate ID “callToAction”.

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

The first occurrence of ID “q” was here.

The first occurrence of ID “callToAction” was here.
