Navigate to this :- http://www.css3pie.com/
Open this in Internet explorer in Chrome and check the difference.
Google chrome supports border-radius and other important css3 functionalities that’s why the styles work in google chrome but IE doesn’t that’s why it failed.
(Internet Explorer 8)
But using css3 pie, it can support border radius and other functionalities. We need to include appropriate attributes in css like
pie-background: linear-gradient(#EEFF99, #66EE33);
