I normally do not care about IE or FF when I write my pages as the people who use them mainly will be using Chrome or Safari and do not have public access.
My inexperience of IE ( avoid it like the plague ) leads me to a few questions in relation to Hype filters and non compatible Browsers
1, Anyone have any known working work arounds (i.e Text-Shadow, blur )
For example these do not work in IE9.
filter: Shadow(Color=white, Direction=130, Strength=10)!important; /* IE Proprietary Filter*/
2, What oldest version you would normally test against and cover. (IE/FF)
Should I for example ignore IE9
3, What is considered best practice when you want to cover most common browsers.
