Hi,

Please try the following codes. It removes the “dark” horizontal box in the slider.

The rgba value is for color. For example if you want blue color, change rgba(0, 0, 0, 0) to rgb(0,0,255)

Please refer to this chart http://www.december.com/html/spec/colorrgbadec.html or any rbga colorpicker.

Thanks!
