HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “” for attribute “type” on element “link”: Expected a MIME type but saw the empty string.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Element “li” not allowed as child of element “nav” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “img” is missing required attribute “src”.
Bad value for attribute “onclick” on element “a”: missing } after property list
Bad value “313px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “142px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
End tag “main” seen, but there were open elements.
Unclosed element “div”.
Warnings:
Potentially bad value “allow-scripts allow-same-origin allow-top-navigation” for attribute “sandbox” on element “iframe”: Setting both “allow-scripts” and “allow-same-origin” is not recommended, because it effectively enables an embedded page to break out of all sandboxing.
