Specifies the width of the range container's start and end boundaries in the LinearGauge UI component.
If you need the LinearGauge UI component range container to be rectangular, set the width of its start/end boundary for this property. If you need the range container to be triangular, assign an object to the width property. Set 0 to the start/end property of the width object and the required numeric value to the width object's end/start property. If you need the range container to be trapezoid, set the required values to the start and end properties of the width object.
