HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “animate-speed” not allowed on element “img” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “href” not allowed on element “button” at this point.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Attribute “ui-sref” not allowed on element “a” at this point.
The “aria-labelledby” attribute must point to an element in the same document.
