I found a very helpful article that show a nice series of CSS3 solutions for Internet Explorer when you are working on projects where a client wants a more accurate cross-browser experience like: Rounded Corners, Box Shadow, Gradients, etc.
For each of the cases the author has added the correspond CSS syntax compatible with all versions of Internet Explorer (IE6, IE7, IE8 & IE9+). The complete list covered in his article includes:
- Opacity / Transparency
- Rounded Corners (border-radius)
- Box Shadow
- Text Shadow
- Transparent Background Colors (RGBA)
- Multiple Backgrounds
- Element Rotation (CSS Tranformations)
I really hope you find this information useful.
