 sanitize-html is tolerant. It is well suited for cleaning up HTML fragments such as those created by CKEditor and other rich text editors. It is especially handy for removing unwanted CSS when copying and pasting from Word.

+sanitize-html allows you to specify the tags you want to permit, and the permitted
+attributes for each of those tags. If an attribute is a known non-boolean value,
