Question

Is there a way to set opacity in a css class, in jquery you could do this:

$(result).parent().css({ 'background-color': '#eeeeee', 'opacity': '0.7' })

any way?
I need to put these to properties in a css class.

Answer 1

There are different CSS properties that are currently required for cross-browser compatibility.

filter:alpha(opacity=50); // For IE
-moz-opacity:0.5;         // Older versions of Mozilla
-khtml-opacity: 0.5;      // For Safari 1.x (I believe)
opacity: 0.5;             // General usage

Personally I’d stick with using jQuery to do this for you since they’ve already developed their method with multiple browsers in mind.
