cross browser - Why did Mozilla...safari have to make CSS more inconvenient with "-moz" and "-webkit" tags? -


odd question maybe, can't find explanation anywhere. don't see why -moz , -webkit tags necessary new css3 properties when of kept simple rest of standard css properties. wouldn't more simple use "box-shadow" browsers instead of using -moz-box-shadow , -webkit-box-shadow... can explain why this? must missing something.

vendor prefixes there properties proprietary or experimental.

most of css 3 specifications not yet candidate recommendations, still being developed , subject change.

many of properties covered specifications candidate recommendations or more advanced still being polished browser vendors don't consider own implementations ready.

the prefixes dropped when properties considered ready mainstream use. you'll see specific example of when firefox 4 released, when starts supporting standard box-shadow declaration rather requiring -moz-box-shadow.
