Notice bar going out of page

I have the notice bar on my webpage,

Somehow the bar going out of the page and is not in center when at the buttom.

See screenshot: https://paste.pics/4HYPB
It is the orange box on the screnshot.

When at the top, it is fixed to the center and between each side of the “box”
How do i get the same at the buttom? OR it fill out to the other site.

I am building a new website where this i seen, normally it is only on the old website, but i am at the part getting all plugins to work with the new theme.
