I've seen you post this particular issue twice in this thread. Perhaps it's not the scrollbars' fault that setting an element's width to 100vw (which is 100% of viewport width) usually requires a scroll? The scrollbars are a symptom that you are setting your child element width too high. Try 100% instead, which should make it 100% of the parent size.

If your intent is to set an element to 100% viewport width with no scrollbar, that's trivially easy to do without jacking around with scrollbar styles.
