Hi folks, bit of philosophy & CSS for y'all. A recent project faced a series of late-noticed serious IE6 hasLayout bugs, and got the team in a panicked discussion in which IE6 bug-fixing best practice got discussed. I ended up re-reading Ingo Chao's excellent article 'On having layout' http://www.satzansatz.de/cssd/onhavinglayout.html, but still ended up with a few questions. I was wondering if thelist's CSS experts might venture answers to these questions:
1. Could it be argued that *any* layout (necessitating complex absolute/relative positioning, overflows, nested lists, etc), carefully built with a thorough knowledge of the Trident box model in mind can avoid having to artificially trigger hasLayout? In other words, no matter how complex a layout's requirements, if it does for whatever specific causes end up suffering from mis-positioned or invisible content due to hasLayout, could I safely say that it should be able to be constructed without resorting to otherwise spurious hasLayout triggers? 2. Ingo's article repeatedly alludes to the classic MS-proprietary CSS zoom:1 trigger being acceptable 'for debug purposes', implying that it should be used to help diagnose hasLayout issues but not to treat them in production. But then concludes that it may be necessary for IE7, but IE5.5-6 should instead use height:1%, even though this is obviously a hack in the sense that it abuses a property for ulterior purposes (unlike zoom, which only affects hasLayout), and will have disastrous effects on any element whose parent also has a set height or non-static positioning. Is it reasonable to assume that this, along with the article's stated preference for conditional comments (rather than CSS syntax-based browser targeting), are purely down to a distaste for invalid CSS? I'm not particularly interested in the legitimacy of that distaste — but I would be interested if there were other reasons I may be missing.
