Not showing full screen! What am i doing wrong here

So I have added an embed to my site and for the life of me I cannot fiqure out how to make it full screen, its so small.

Here is a screen shot of it being in the corner and not full width and height.

Here is access to see the designer view:

You have the embed placed in a container, inside a section that has the Grid layout applied. The container is set to expand to 100%, but because it’s inside the grid, it conforms to the grid’s layout, so it’s filling 100% of that grid cell, which is only 50% of the whole page width. So, just pull it out of the grid and into its own container should fix you right up.
