I want to change the icon to my image, I\'ve looked through the CSS reference guide but I can\'t seem to find anything relevant. Is it even possible? Doesn\'t matter if it i
If you want to remove the thumb background color and only have the image(semi-transparent ones like round button) then you should also -fx-background-color:transparent; unless you will have the background
.slider .thumb {
-fx-background-image :url("sider-round-thumb-image.png");
-fx-padding: 16; /* My thumb image is 33x33 pixels,so padding is half */
-fx-pref-height: 28;
-fx-pref-width: 28;
-fx-background-color:transparent;
}
