I think this could be confusing.  Code would be easier to read if '%w' is used for width and '%h' is used for height. So for example;\r\n```\r\ndiv {\r\nmin-height: 100%w;\r\n}\r\narticle {\r\nmax-width: 150%h\r\n}\r\n```\r\n\"%w\" and \"%h\" are only suggestions: they could be just \"w\" and \"h\" (subject to comments in other threads).\r\n\r\nIf \"tr\" is favoured, I suggest it should be a percentage value like \"vw\" and \"vh (as was proposed for \"ew\")..\r\n"}}
