Seeking to Narrow width of survey "progress bar."

Not sure if this is the correct channel, but posting for assistance to inquire if there is a way to custom change (make more narrow) the default Progress bar? For the current survey is stretches the entire width of the page, but I'd like for it to be more narrow.

The survey contains about 55 questions in total, but through the logic flow the max question set any respondent will field would only be ~20.
(@moderator please advise or redirect this question to the appropriate channel if this is not the correct forum).

Thanks
