I'm CSS web designer, any one can fix this problem as following for me?
Actually in IE7, we can use filter:alpha(opacity=70),then the problem is fixed.
But when I use jQuery's something like fadeIn or fadeOut, the problem appear in IE7, especially for PNG image, its transparent becomes black color. I'm using jQuery fadeIn and fadeOut are using in sliding, those images are buttons, there got 2 layers, one is for normal, another is for hover.
I know the last way, it is making the transparent become same with its background, but it is too much buttons there, spending my time and also the backgrounds are not always the same, quite flexible. So it is not worth to make that decision.
