Question

I set a div style programicaly like below:

oDiv.Style.Add("text-align", "center");

it works in IE ,But not in FireFox,

for FireFox I must write this one:

oDiv.Style.Add("text-align", "-moz-center");

How could I have both?because if I write both ,just the second one works, please help me.

Answer 1

thanks All.finally I could solved it with this :

.newClas{
   text-align: -moz-center;
   #text-align: center;
}

the # sign must be before next line in the css class
