CSS for rangeSlider

I need to customize my RangeSlider like this photo.

We can modify the min and max of rangeSlider. Anybody can give some advices?

The underlying JavaScript slider library that Bokeh uses for the built-in Slider does not support anything like that. You will have to find a JavaScript slider library that you like / that suits your needs, and make a custom extension to wrap it, as described in the User’s Guide chapter Extending Bokeh.
