Div background-color does not extend to child divs

Question

I have a container div with several child divs within this. The parent div has a background-color, however, this doesn\'t seem to be extending to the last couple of child divs.

Answer 1

.container {
  display: block;
  max-width: 600px;
  height: 100%;
  margin: 20vh auto;
  padding: 0 3%;
  background-color: white;
  text-align: justify;

  overflow: auto;
}

Your checkout is floating, so it doesn't apply correctly to how the container behaves
