Yes, that's true. You might want the ability to do lazy style computations, even if your primary strategy was eager, just for cases like this. It'd be interesting to know how often it's beneficial to not just go ahead and compute the styles for e.g. display: none subtrees, though. Presumably they are on the page because eventually some event will cause them to be displayed, right? (Quite hypothetical without data, of course.) - Seth _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
