Bad value “Cache-control” for attribute “http-equiv” on element “meta”.
Element “style” not allowed as child of element “article” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “alt” not allowed on element “input” at this point.
Element “style” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)

The “align” attribute on the “img” element is obsolete. Use CSS instead.
