An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “content” not allowed on element “span” at this point.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Bad value “100%” for attribute “height” on element “img”: Expected a digit but saw “%” instead.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Warnings:

The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
