HTML markup errors and warnings
(Rescan now...)
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “figcaption” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “b” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “main” role is unnecessary for element “main”.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
