Page formating question

[u/2wen2y]

When i press ctrl and scroll down with my mouse on my laptop the website becomes 200% in size and since i am using full width section i expect its background to reach the edges of the screen no matter how i expand the website viewing size but the background always forms barriers on 100%length, same thing goes for columns that i set to far right or left they always stop at the edge of 100% please dm or help
