特定高度的部分的背景图像

Posted 2021-04-08

我真正想要实现的是将背景图像放到特定的高度，就像我有一个包含两个div的部分我给了该部分一个背景图像，这是

    background-image: linear-gradient(-207deg, #0EC573, #0093FF);

现在我要实现的是背景图像覆盖了整个第二个div和第一个div的某些部分

答案

使用它（参见JSFiddle：https://jsfiddle.net/Lfxja1e5/7/）：

 background-size: 100% 70%;
 background-repeat: no-repeat;

**如果你想在底层使用它：

background-position: bottom;

 .company{
      background-image:linear-gradient(-207deg,#0EC573, #0093FF);
     background-size: 100% 70%;
     background-repeat: no-repeat;
      background-position: bottom;
    }
