Followup to #11990

Created by: Steve-OH

Apologies for not commenting sooner, but I have been off the grid in Colombia for the past two weeks.

The JSbin screenshot you posted in #11990 (closed) shows exactly the problem that I'm talking about: Despite being contained in a column, the widths of the two controls are not related. That is, the width of the slider is not constrained to the column width in the way that the width of the text box is. This becomes apparent when you resize the browser window: the text box resizes itself appropriately; the range slider does not.
