# What are the possible options for the Appearance option of IntervalSlider?

IntervalSlider has a styling option Appearance -> ..., where possible options include "ThumbAppearance" which allow one to change the styling of the little drag handles as shown below.

How can I find what other valid options there are? For example I wish to change the blue shading of the interval to red.

IntervalSlider[Dynamic[int], {0, 100, 1},
Appearance -> {"ThumbAppearance" -> {
Dynamic[Framed[First[int], Background -> LightPurple]],
None,
Dynamic[Framed[Last[int], Background -> LightPurple]]}}
]


• An analogous ThumbAppearance option for Slider would also be useful. – Ronald Monson Jul 28 '17 at 23:47
