Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Attribute “scr” not allowed on element “img” at this point.
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.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “td_uid_4_5b88561cb2b67”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
