CSS: “justify-content”: “baseline” is not a “justify-content” value.
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.
Attribute “defer” not allowed on element “iframe” at this point.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
Bad value “100%” for attribute “height” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
