That is not a fix - just a cosmetic change that does not solve anything. display/flow MUST BE [1] different properties as they define orthogonal concepts. We should be able to define them separately. main { display: block; flow:grid; } @media handheld and (width < 100mm) { main { flow:vertical; } } Yet none from display shall go to visibility:none (as in my Sciter [2]). I've seen too many times errors like this: main table { display:none; } main.full table { display:block; } Which is obviously wrong, <table> element should have display:table or display:inline-table; [1] https://tools.ietf.org/html/rfc2119 https://tools.ietf.org/html/rfc2119 [2] https://sciter.com https://sciter.com
