The “leftmargin” attribute on the “body” element is obsolete. Use CSS instead.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
The “center” element is obsolete. Use CSS instead.
When the “srcset” attribute has any image candidate string with a width descriptor, the “sizes” attribute must also be present.
