Images not getting bigger with screen size


I cannot seem to figure out why the images in my “How It Works” section are not getting bigger as screen size increases. In fact, they seem to do the opposite and get smaller. In particular, I am talking about the colorful shapes behind the text.

Ideally, as breakpoints get bigger, I would want the “How It Works” in “Features Section” to stay centered and grow larger responsively.

Picture of what it should look like when viewing website in 1440p+

Any help appreciated!

Thanks in advance,
