I'm trying to remove extra padding that keeps displaying below my uploaded videos, specifically for Mobile view only. It shows a very small amount in edit mode, but when I look at the live mobile version on my phone additional white space is added. I added code to make the video display 16:9 ratio. Anyone know the code to keep this from happening? See below.
