popover slider value

[sjfp]

On a vis have a load of buttons that when pressed brings up popover slider in the same position of the vis for all buttons.
Using the following CSS Code:

.popover.control.control-slider.control-slider-h.slider-h.show {
  background-color: #888888 !important;
  transform: scale(.9) !important;
top: 700px !important;
left:290px !important;
  width:345px;
}

How can I add the progress value to the popover control, need it to be there all the time, would also be nice to put the %value  to the right side of the control. Also wan tot remove the Left and right hand side buttons, so its just the slider.

Thanks for any input
