A little hack to set Cross-Browser opacity.

.setOpacity {
      opacity: .75; /* Standard: FF gt 1.5, Opera, Safari */
      filter: alpha(opacity=75); /* IE lt 8 */
      -ms-filter: "alpha(opacity=75)"; /* IE 8 */
      -khtml-opacity: .75; /* Safari 1.x */
      -moz-opacity: .75; /* FF lt 1.5, Netscape */
}
