HTML markup errors and warnings
(Rescan now...)
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Bad value “true” for attribute “async” on element “script”.
Stray end tag “a”.
Attribute “target” not allowed on element “span” at this point.
Attribute “ss-container” not allowed on element “div” 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.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
