Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “slide-title”.
No “p” element in scope but a “p” end tag seen.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “slide-title” was here.
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).
