Interactice pricing component / works on firefox + chrome

I learned a couple things from doing this project

• chrome and firefox require seperate rules to style the input range
• chrome doesn't have a pseudo class to style the progress bar like firefox does(-moz-range-progress) so I had to use JS to achieve the desired effect
• using aria role on my toggle switch and JS to make it work with keyboard controls since it is a label and not a button

all feedback is welcome
