以下内容适用于我在Microsoft、Chrome和Mozilla上的特定div元素：

div.rightsidebar {
    overflow-y: auto;
    scrollbar-width: none;
    -ms-overflow-style: none;
}
div.rightsidebar::-webkit-scrollbar { 
    width: 0 !important;
}

以下内容适用于我在Microsoft、Chrome和Mozilla上的特定div元素：

div.rightsidebar {
    overflow-y: auto;
    scrollbar-width: none;
    -ms-overflow-style: none;
}
div.rightsidebar::-webkit-scrollbar { 
    width: 0 !important;
}

这将在正文中：

<div id="maincontainer" >
    <div id="child">this is the 1st step</div>
    <div id="child">this is the 2nd step</div>
    <div id="child">this is the 3rd step</div>
</div>

这是CSS：

#maincontainer
{
    background: grey;
    width: 101%;
    height: 101%;
    overflow: auto;
    position: fixed;
}

#child
{
    background: white;
    height: 500px;
}

此外，所有浏览器都可以在没有滚动条的情况下滚动。

CSS

.keep-scrolling {
  background-color: #EEE;
  width: 200px;
  height: 100px;
  border: 1px dotted black;
  overflow-y: scroll; /* Add the ability to scroll the y axis */
}

/* Hide the scrollbar for Chrome, Safari and Opera */
.keep-scrolling::-webkit-scrollbar {
  display: none;
}

/* Hide the scrollbar for Internet Explorer, Edge and Firefox */
.keep-scrolling {
  -ms-overflow-style: none;  /* Internet Explorer and Edge */
  scrollbar-width: none;  /* Firefox */
}

SCSS

.keep-scrolling {
    background-color: #EEE;
    width: 200px;
    height: 100px;
    border: 1px dotted black;
    overflow-y: scroll; /* Add the ability to scroll the y axis */

    /* Hide the scrollbar for Internet Explorer, Edge and Firefox */
    -ms-overflow-style: none;  /* Internet Explorer and Edge */
    scrollbar-width: none;  /* Firefox */

    /* Hide the scrollbar for Chrome, Safari and Opera */
    &::-webkit-scrollbar {
       display: none;
    }
}

HTML

<div class="keep-scrolling">
</div>

另一个简单的工作小提琴：

#maincontainer {
    background: orange;
    width: 200px;
    height: 200px;
    overflow: hidden;
}

#childcontainer {
    background: yellow;
    position: relative;
    width: 200px;
    height: 200px;
    top: 20px;
    left: 20px;
    overflow: auto;
}

父容器上隐藏溢出，子容器上自动溢出。易于理解的

只需编写以下代码：

::-webkit-scrollbar {
  width: 0px;
}

Or

::-webkit-scrollbar {
  display: none;
}
