What should be alerted here? <style> :root { var-a:a; var-b:var(a)b; } </style> <script> var cs = getComputedStyle(document.documentElement, ""); alert(cs.getPropertyValue("var-b")); </script> I take it that the computed value of var-b is a stream of two ident tokens, with no white space between. Should this be represented by "a/**/b"? In nearly all situations it won't matter if we treat the value of var-b as having a white space token between the two idents. But it could certainly change the validity of a property, for example: :root { var-a:1px; font-size: calc(1px +var(a)); }Received on Tuesday, 27 August 2013 07:06:24 UTC
