There seems to be an error in the documentation. WhiteListType.RELAXED allows the tags returned from org.jsoup.safety.Whitelist#relaxed which includes div and span. I'll update the SafeHtml documentation to clarify it.

WhiteListType.BASIC doesn't allow div, but it does allow span. If that's not good for you, then you can use WhiteListType.SIMPLE_TEXT and add any missing tags using SafeHtml#additionalTags.
