HTML markup errors and warnings
(Rescan now...)
Errors:
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.
Attribute “disabled” not allowed on element “li” at this point.
Element “img” is missing required attribute “src”.
Element “div” not allowed as child of element “h6” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “span” 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:
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
