NOTE: style refers to style declarations within other at-rules, such as @media.
IMPORTANT: Blacklisting @namespace while whitelisting other types of at-rules can lead to errors. Property declarations in @font-face and @viewport are not sanitized.
NOTE: The style tag is blacklisted by default, as opposed to the style attribute.
NOTE: Protocol-relative URLs, for example, //GitHub.com, are whitelisted by default, as are other relative URLs.
