Using CSS3 rgba()

I have used a CSS3 declaration

background-color: rgb(252,190,200); 
background-color: rgba(252,190,200,.7); 

Most modern browsers use the rgba() value; IE8 uses the rgb() value but IE7 ignores both. Any ideas how to get IE7 use the rgb() value?

Thanks

Thanks David. That is just what I need.

No offence, but did you ever think of checking Google for this?
