Custom Numeric Range Slicer

[Sssman]

Hi,

I was trying to package this custom slicer, I installed correct dependancies but still facing an issue with node_module, can't import the min.css from node_module.

I am basically looking for a numeric range slicer where I can adjust the width of the boxes/container, has sync slicers and bookmark support. I like the one that's provided by microsoft but the reason I can't use it is because I can't edit the box width, if anyone can help me with that I would really appreciate it.
