html - 如何为移动设备缩放此视差中的背景图像？

Question

我正在尝试设置一个流畅的模板，我也可以将其用于响应式设计视口(viewport)。但是现在，当我尝试调整浏览器窗口大小时，它不会缩放，而在我的 iPhone 上，我只能看到标题图形的左上部分。在移动设备上，背景图像非常大且模糊，但在我的 test website 上看起来还不错.任何帮助将不胜感激

你需要添加 background-size: 100% auto ，这样你就可以根据屏幕分辨率做出响应

section.module.parallax {
  background-position: center;
  background-repeat: no-repeat;
  background-attachment: fixed;
  -webkit-background-size: 100% auto;
  -moz-background-size: 100% auto;
  -o-background-size: 100% auto;
  background-size: 100% auto;
  max-width:100%;

}
