HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute for the “style” element is not needed and should be omitted.
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “x-mark-icon” 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).
Errors:
Attribute “asp-compact” not allowed on element “div” at this point.
Duplicate ID “x-mark-icon”.
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.
The “aria-labelledby” attribute must point to an element in the same document.
The “aria-describedby” attribute must point to an element in the same document.
