How to extend the bottom of an svg block while adding others?

Question

css

Hello, I have a question. There is a background, on top of it there is a block with background svg. It is necessary that when I add some content on top of this block, this block stretches to the end of the screen, and does not stand statically. And it turns out when adding content, it remains in place, and the screen is pulled out and the background is shown.
