filter:alpha(opacity=90);
-khtml-opacity: 0.9;
-moz-opacity:0.9;
opacity: 0.9;

Now for the different ways of setting opacity…

For Internet Explorer:

filter: alpha(opacity=90);

For Mozilla:

-moz-opacity: 0.9;

For Safari (current):

opacity: 0.9;

This is the important one. It is the current standard supported by Safari, Opera and Firefox

For Safari (old):

-khtml-opacity: 0.9;

This is for older versions of Safari, back before it adopted webkit (which is what you use for something like round borders).
