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”.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Element “div” not allowed as child of element “cite” in this context. (Suppressing further errors from this subtree.)
Element “h4” not allowed as child of element “cite” in this context. (Suppressing further errors from this subtree.)
Element “h5” not allowed as child of element “cite” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “sign-up-modal”.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Warnings:
The first occurrence of ID “sign-up-modal” was here.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
