Question

我一直在尝试使用SASS将背景图像设置到我的Rails应用程序但是当我尝试时：

.header {
  display: table;
  height: 100%;
  width: 100%;
  position: relative;
  background-image: image-url("sky.png") no-repeat center center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

图像未加载，但是当我尝试时：

background-image: image-url("sky.png");

图像部分加载。任何人都知道为什么会这样吗？我该如何解决这个问题？

Answer 1

所以我发现你和我有同样的问题，经过数小时和数小时的挖掘，我终于找到了解决1/3图像问题的方法。我不是开发人员，这可能是完全错误的但是在时尚组合中包含的css中有一个部分调用.text-vertical-center我在最初的帖子中没有在你的.css中看到它。为了正确显示图像，我发现你需要添加

height: 963px;

这解决了我的问题。我看到你发布这个已经好几个月了，但我真的希望它可以帮助你或其他人。如果没有正确的方式在.css中显示图像，请随时留下评论。
