HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “complementary” role is unnecessary for element “aside”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.
Attribute “pagespeed_no_defer” not allowed on element “script” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
