+It is very much a work-in-progress, and implementers should reference CSS2.1 for now.

+The <dfn>root inline box</dfn> is an anonymous inline box
+which is automatically generated to hold
+all of the <a>inline-level</a> contents of a <a>block container</a>
+(if it has any).
+It inherits from its parent <a>block container</a>,
+but is otherwise unstyleable.
