RGBA to css hex code?

[Texas]

I'm trying to create a css gradient that will go over a div and make it fade from transparent to opaque. However, everything but IE uses RGBA. IE uses an eight character hexidecimal, and I need to convert the RBGA numbers to a hex number, but I have no idea how. Any help? I searched around for some stuff but couldn't find anything that worked.

You should be able to do a straight conversion. E.g., 0 = 0 and ff = 255. Write a function that translates from hex to decimal (or vice versa, depending on which direction you need), then split your string every two characters and run them each through that function.

Hint:

hexString = yourNumber.toString(16);
yourNumber = parseInt(hexString, 16);

Thanks, I actually had figured it out just a second ago and I'd come to remove my post, but thanks for taking the time to explain.
