Single JavaScript (library) to fix all IE 6 issues and make it compatible with css3

Question

Is there any JavaScript (library) or any other solution, through which we can fix most of IE6 issues like PNG fix and also make IE6 to support CSS3 properties?

Answer 1

No. CSS3 support in IE6 is not going to happen. There is library available that will make IE6 more-or-less compatible with IE7:
