如何在CSS中使背景图像无响应？

.background {
  background-image: url('background.jpg');
  background-size: cover; /* 或者使用contain */
  background-repeat: no-repeat;
}

.background {
  background-image: url('background.jpg');
  background-position: center;
  background-repeat: no-repeat;
}

.background {
  background-image: url('background.jpg');
  background-repeat: no-repeat;
}

@media (max-width: 768px) {
  .background {
    background-size: cover; /* 或者使用contain */
  }
}
