HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Attribute “"” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “cache-control” for attribute “http-equiv” on element “meta”.
Bad value “pragma” for attribute “http-equiv” on element “meta”.
Bad value “expires” for attribute “http-equiv” on element “meta”.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “link” 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.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
