how to add transparent quotation marks to revolution slider

Hi, I have put unicode quotation marks as a text on top of the image and added as advanced layer css

{
opacity: 0.5;
filter: alpha(opacity=50);
}

The quotation marks are transparent now in the add-on but not on the web page: http://humanisticevolution.com/en/home/

Any ideas?
THANKS!
