You may remember when JavaScript was a dark art. It earned that reputation because, in order to do anything with even the teensiest bit of cross-browser consistency, you had to fork your code for various versions of Netscape and IE.

Enter Aaron Gustafson’s eCSStender, a JavaScript library that lets you use CSS3 properties and selectors while keeping your code fork- and hack-free.
