Or is it safe to use when IE6 / IE7 is heavily used?
The whole idea of ββjQuery is that it normalizes the behavior of browsers. Everything should work in any browser on a "compatible" list that includes IE6 and up.
However, note that browsers may be added or removed from a compatible list in the future; for example, jQuery 2.0 will only support IE 9 or later .
No, the implementation of the jQuery selector is not dependent on CSS3 support.
And yes, you can use all jQuery features in IE6 / 7. jQuery works in IE 6.0+, FF 10+, Safari 5.0+, Opera, Chrome, as indicated on their website.
