Full screen "Edge Animation" inside Muse?

I am trying to create a full screen Edge Animation and insert it into Muse?

I'm pretty good with both programs but after making making the Edge Animation 100% wide & 100% height it doesn't fill the entire browser even though it is lining up with both sides of the page in Edge.

Also, if I zoom out in my browser it stays on the left instead of the center.

I am basically trying to create a highly animated "landing page" for my website using all Edge although I might use a footer in Muse.
