How to stretch the color to the whole background?

Question

css

Here the essence of the question is that I need to stretch the gray color to the entire background of this part of the page. The bottom white part will be another part so it can't be changed, so I can't assign a gray color to the entire body block.
Can anyone help?

Good afternoon, I'm just a beginner in the level, but why do you need to set the color for the entire body. Divide the site into blocks, there is a section semantic tag. And for each block, set the background color separately.
