Bad value “Expires” for attribute “http-equiv” on element “meta”.
Bad value “Pragma” for attribute “http-equiv” on element “meta”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray start tag “script”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray end tag “i”.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
