I am designing a web application with css3. Every one knows that lot of css3 properties like gradients, border-radius, box-shadow, animate, border-image, background-rgb, last-child, nth-child etc.. will not work in earlier IE versions such as IE8,7,6. some of the java script libraries like css3 pie can be used to make Internet Explorer 6-9 capable of rendering several of the most useful CSS3 decoration features such as gradients, border-radius, border-shadow, border-image(not Last-child, nth child properties) but some of my friends facing issues with that and told me that it is not reliable.
Is there any other js library or polyfills which will support most of the css3 decoration features including child properties without using filter like compass?
Thanks.
