I just found a slightly more helpful description of the intended effects of X-UA-Compatible headers and emulation modes on MSDN here: http://msdn.microsoft.com/en-us/library/cc288325(v=vs.85).aspx#SetMode. It turns out I'd got things wrong, since setting a browser mode in the DOM inspector forces standards mode — as does setting the meta tag value to IE#. Setting the value to Emulate=IE# apparently does more accurate emulation, since it allows for standards or quirks mode to be established based on the usual factors. Further inaccuracy on my part: 'compatibility mode' apparently forces IE7 in standards mode. So for those still reading, I retract all of my verbose nonsense 2 emails back. > <http://css-class.com/test/bugs/ie/renderingbands-image-size.htm> > I would please appreciate a check of the above test case in the the latest > version of IE9 since I have IE9 RC. I couldn't find instructions on how to perform the tests whose results are listed in that table (page looks substantially different for each of the last 3 versions of IE though!). However: 1. Rendering bands: Can't replicate any of the bugs 2. Escaping floats Can replicate all the bugs forced IE7 mode and compatibility mode 3. Sons of suckerfish Can't replicate any of the bugs 4. Recalculate offset Can't replicate any of the bugs 5. Button crash Can't replicate 6. Background flicker Can't replicate any 7. Em font-sizing inheritance Can't replicate 7. Em font-sizing inheritance Can't replicate 8. Strange peekaboo In IE7 mode and compatibility mode, the blue-bordered div simply doesn't appear unless the viewport width is less than 337px, and although its top offset is immediately within the parent's border (as one would hope), the 'test' divs inside it within in clear the red-bordered div. At viewport sizes under 262px, the blue border still wraps the content, but the background colour only fills the top 18px. This doesn't seem to be the behaviour you're describing, but then it's inherently weird stuff. I stand disconcerted and corrected!
