关于 css:HTML 背景附件：已修复。滚动后背景被掩盖

HTML background-attachment: fixed. The background gets covered up after scrolling

我基本上是在尝试创建一个背景图像，这样它将永远固定在某个位置。但是，似乎如果 div 内部有太多内容并且我向下滚动，图像仍然保持固定，但我向下滚动的次数越多就会”覆盖”。

页面顶部的视图看起来很好
向下滚动一点后，背景开始被覆盖(可以看到图像仍然固定在原位)

代码片段如下。我在内部 div 中添加了许多新行来显示问题

您需要将 overflow:scroll; 添加到 .bg 类

bg{
height: inherit;
background-image: url(http://placekitten.com/200/300);
background-position: center center;
background-repeat: no-repeat;
background-size: cover;
background-attachment: fixed;
overflow:scroll;//new selector added
}

查看实时预览

把你的背景图片放在你的身体上。

另一个解决方案是：将溢出设置到您的 .bg 类中 overflow-x:auto;

或者只是添加

overfloaw:scroll

在bg类中

删除 html, body 中的 height 100% 并删除 .bg 中的 height: inherit;。那应该可以。
