Attribute “type” not allowed on element “div” at this point.
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Bad value “screen and (-webkit-min-device-pixel-ratio: 2), (min-resolution:192dpi)” for attribute “media” on element “source”: Expected a CSS media feature but saw “-webkit-min-device-pixel-ratio” instead.
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “link” role is unnecessary for element “a”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
