I have a set up with several sections that have a full-screen width and height. Whether I position them absolute or relative the overflow still doesn't work.
section {
  height: 100vh;
  width: 100vw;
  overflow: hidden;
}
#a {
  background: linear-gradient(1deg, #9f00b8, #2a032d);
  position: absolute;
}
#b {
  background: linear-gradient(1deg, #25cc00, #2a032d);
  left: 100vw;
  position: relative;
}
