Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “hr” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
The element “button” must not appear as a descendant of the “a” element.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
