For the all internet browser has there common standards and standards of their own so some feature in style may not be same in another browser. Now a days we face most of the problems for the styles in internet explorer, all other browsers supports the same css properties but internet explorer will not support it. like this way one of the main css property we use daily is opacity. All other browser support opacity property in the name ‘opacity’ but internet explorer does not support opacity keyword,we have to use opacity inside a filter property. Instedof opacity we have to use filter , for example filter: alpha(opacity = 50);
So briefly the opacity feature of css does not work on internet explorer IE, to overcome that use filter option.
filter: alpha(opacity = 60);
Note: The value of filter is different from opacity
