A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.

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

Text not allowed in element “ul” in this context.

Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.

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