However it would be better to clarify how nested @host @-rules work. For example, suppose that we have the following tree: <hostA> #shadow-root <hostB> #shadow-root <style> @host { @host { * { border: 1px solid green; } } } </style> .... So how should the above nested @host @-rules work? I think, at least, we have four options: (a) The above nested @host @-rules should be applied to hostA, (b) The above nested @host @-rules should be disallowed. So treat as "@host { * { border: 1px solid green; }". hostB should have 1px solid green border. (c) The above nested @host @-rules should be disallowed. Ignore. (d) Other options... I would like to know which would be the best option. 90900 1 dglazkov 2013-07-17 22:31:17 +0000 @host is dead.
