A Range is an interactive component that lets the user swiftly slide through possible values spread over the desired range.
Detailed documentation and more examples you can find in our Bootstrap Range Docs
Basic example
Create custom <input type="range"> controls with .form-range.
The track (the background) and thumb (the value) are both styled to appear the same across
browsers. As only Firefox supports “filling” their track from the left or right of the thumb
as a means to visually indicate progress, we do not currently support it.
Min and max
Range inputs have implicit values for min and max—0 and
100, respectively. You may specify new values for those using the
min and max attributes.
