滚动时增加不透明度

Question

当我滚动时，我希望文本以与图片相同的方式显示，并且不透明度增加。你能帮我解决这个问题吗？

Answer 1

您可以在文本上设置2个图像（在顶部和底部），不透明度，位置固定或绝对，滚动文本图像将在底部文本和顶部文本上方:) 希望我帮助你!!祝好运！ ：）

Answer 2

您可以使用背景渐变创建两个<div>来完成此效果。

以下是两个显示我的意思的JSFiddles：

Answer 3

尝试this代码，类似代码的示例：

body {
    height: 500px;
}
.Top {
    position: absolute;
    background-image: url(http://afkarco.ir/images/Bottom.png);
    top: 0;
    right: 0;
    width: 100%;
    height: 100px;
    z-index: 10;
}

marquee {
    margin: 100px 0;
    height: 500px;
}

.Bottom {
    position: absolute;
    background-image: url(http://afkarco.ir/images/Top.png);
    bottom: 0;
    right: 0;
    width: 100%;
    height: 100px;
    z-index: 10;
}

Answer 4

我猜你的图片中的网站使用堆叠的.png -s来创建效果。如果您不想使用图像，可以使用带有框阴影的封面div伪造它：

html,
body {
  height: 100%;
  width: 100%;
  padding: 0;
  margin: 0;
}
p {
  padding: 20px 50px
}
.pCover {
  position: fixed;
  top: 0;
  height: 100%;
  width: 100%;
  background: transparent;
  box-shadow: 0 0 30px 40px #fff inset;
}

<div class="pCover"></div>
