透明背景滚动条显示在内容顶部 [英] Transparent background scrollbar displays on top of content

问题描述

我想实现这一目标：



我已经实现的目标：

I want to achieve this:

What I already achieve:

.dropdown-menu { //container
    overflow-y: overlay;
    background-color: transparent;
}
.dropdown-menu::-webkit-scrollbar {
    width:10px;
}
.dropdown-menu::-webkit-scrollbar * {
    background:transparent;
}
.dropdown-menu::-webkit-scrollbar-thumb {
    background:$blue !important;
    border-radius: 6px;
}

有人对我如何做到有任何想法吗？如何使物品停留在其容器和容器的滚动条之间，使它们看起来像设计？
我尝试将z-index放入元素中，但似乎不起作用。

Does someone have any ideas how I can do that? How can I make the items stay between their container and the container's scrollbar so they looks like the design? I tried putting z-index in the elements but seems not to work.

推荐答案

只需在主体中切换单位标记从％到 vw
，您将获得内容过多的影响。

Just switch the unit in body tag from % to vw and you will get the over content effect.

body {
  width: 100vw;
  overflow-x: hidden;
}

body::-webkit-scrollbar {
  width: 0.7em;
  background: transparent;
}
body::-webkit-scrollbar-thumb {
  background: #c0392b;
}
