IE7 {css2: auto; }

IE7 is a JavaScript library that makes the explorer work by standards. It eliminates many problems with css, makes the correct processing of semi-transparent PNG under IE5 and IE6.

IE7 loads and parses stylesheets in a format understandable to the explorer. After that, it becomes possible to use CSS2 / CSS3 functions without css hacks.

The light version of the script is included in your HTML / XML document. No change in markup or css styles is needed.
