Make banner slideshow with autoscroll full bleed

Is there a way to make the banner slideshow (that is auto-scroll with code) full bleed so the navigation bar has no black background upon first load?

Also, is there a way to make the arrows on the banner slideshow more minimal? Like without the circle possibly?

Thank you!! Is the banner slideshow being full bleed possible?

Also, inserted the code above to the custom CSS and nothing changed. Am I inserting it int he right place?
