IE not supported css property "opacity" yes? In IE not working: testObj.style.opacity = 0.5
And for IE, I use this code: testObj.style.filter = 'alpha(opacity=' + 50 + ')';
But As I understood, this variant: 'alpha(opacity=' + 50 + ')'; is for old IE versions and not the best variant, there is a better variants, but what is this variants, i am not found.
Please tell me, where is the optimal variant for transparency in IE?
P.S. Excuse me for many times word "variant", i know english not good
