I am creating a Beamer presentation in which I am presenting some Julia code. By marking each frame as `fragile`, the styling looks great and goes edge to edge for a really nice finish. See screenshot

However, instead of the usual 4:3 aspect ratio of Beamer slides, I am using `BeamerPoster` to create a bigger 16:10 slides. This works great and can contain a lot more information, except the styling for the Julia code. The stylized box does not go from edge to edge and and considers only the width of the original 4:3 beamer slide. See attached figure.

Is there a way to modify the [Latex style file](https://github.com/wg030/jlcode/blob/master/jlcode.sty) to have the stylized box go edge to edge?
