price and floating buttons

I don’t know if it’s too much to ask, but can you put an option so that the box where it shows the price and the buttons is floating? and also on smartphones and tablets it adjusts to the bottom of the screen and is floating, this so that the customer always has the option to see the price and does not have to slide to the bottom and then scroll to the top again
