HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “button” role is unnecessary for element “button”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Duplicate attribute “class”.
When the “srcset” attribute has any image candidate string with a width descriptor, the “sizes” attribute must also be present.
Element “img” is missing required attribute “src”.
Attribute “news” not allowed on element “article” at this point.
Element “div” 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The “align” attribute on the “img” element is obsolete.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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “aria-controls” attribute must point to an element in the same document.
