(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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).
Errors:
Bad value “https://fonts.googleapis.com/css?family=Open+Sans:300,300i,400,400i,600,600i,700|Roboto:400,400i,500,500i,700,700i” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
