祝你们一切顺利。
所以我有一个带有背景图像的部分，我想在背景图像上添加一个线性渐变。
我的目标是：
x1c 0d1x的数据
到目前为止，我有一个带有背景图像的div。
当前CSS：

background-image: url("../pixels/lastCallToActionBg.jpg");
background-position: center;
background-repeat: no-repeat;
background-size: cover;

字符串

在区域内做一个div，它将作为一个蒙版，并将这个蒙版的渐变设置为其中的背景。
掩码的css看起来像这样：

position: relative;
top: 0;
left: 0;
width: 100%;
height: 100%;

字符串
因此它将遍布父元素（节）

section {

    width: 100vw;
    height: 10rem;
    background: url(https://www.yannickdixon.com/wp-content/uploads/2016/12/161124-golden-seaside-sunset-photography-print.jpg);
}

.overlay {

position: relative;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;

试试这个

body {
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  background-image: url(https://actionseaze.com/wp-content/uploads/2020/02/sunset.jpg), 
  -webkit-linear-gradient(
    top,
    rgba(0, 0, 0, 1) 0%,
    rgba(0, 0, 0, 1) 1%,
    rgba(0, 0, 0, 0) 35%,
    rgba(0, 0, 0, 0) 100%
  );
  background-blend-mode: color;
  height: 100vh;
}

你也可以使用::after css psuedo-element来实现这一点。

body::after{
    content: '';
    linear-gradient(
        top,
        rgba(0, 0, 0, 1) 0%,
        rgba(0, 0, 0, 1) 1%,
        rgba(0, 0, 0, 0) 35%,
        rgba(0, 0, 0, 0) 100%
  );
    position: absolute;
    inset: 0;
    width: 100%;
    height: 100%;
