Errors:
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “div” is missing one or more of the following attributes: “role”.
When the “srcset” attribute has any image candidate string with a width descriptor, the “sizes” attribute must also be present.
Bad value “(min-width: 37.5625em) and (max-width: 64em) 44vw, (min-width: 64.0625em) 222w, 25vw” for attribute “sizes” on element “img”: Expected units (one of “em”, “ex”, “ch”, “rem”, “vw”, “vh”, “vmin”, “vmax”, “cm”, “mm”, “q”, “in”, “pc”, “pt”, “px”) but found “w” at “…n-width: 64.0625em) 222w,”.
The “aria-controls” attribute must point to an element in the same document.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
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).
