Question

如何缩放背景以适应任何屏幕？我尝试了background-size: cover和height: auto，但没有任何作用！有任何想法吗？我似乎找不到任何可行的东西。我很感激你能解决这个问题。

您可以使用排名技巧，将全部设置为0。

html {
  background: URL("https://lh3.googleusercontent.com/-lYQ3vQHE3Mo/VrVKGwg8pqI/AAAAAAAADMQ/QKjs5ALViKo/w530-d-h253-p-rw/desk%2Bbackground.png") #363634 no-repeat center top;
  background-size: cover;
  position: fixed;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}

或同时设置width:100%和height:100%。

html {
  background: URL("https://lh3.googleusercontent.com/-lYQ3vQHE3Mo/VrVKGwg8pqI/AAAAAAAADMQ/QKjs5ALViKo/w530-d-h253-p-rw/desk%2Bbackground.png") #363634 no-repeat center top;
  background-size: cover;
  position: fixed;
  width: 100%;
  height: 100%;
}
