如何实现此背景滚动效果？

.container {
  width: 100%;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.background {
  width: 100%;
  height: 100%;
  background-image: url("background-image.jpg");
  background-size: cover;
  animation: scroll-background 5s linear infinite;
}

@keyframes scroll-background {
  0% {
    background-position: 0%;
  }
  100% {
    background-position: 100%;
  }
}

// 滚动到页面底部
window.scrollTo({ top: document.documentElement.scrollHeight, behavior: 'smooth' });

// 滚动到页面顶部
window.scrollTo({ top: 0, behavior: 'smooth' });
