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;
}

这个帖子已经得到了很多人的回复，但我觉得它的解决方案可能会简单得多。

/* Hide scrollbar for Chrome, Safari and Opera */

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

/* Hide scrollbar for Internet Explorer, Edge and Firefox */

.container {
    -ms-overflow-style: none;  /* Internet Explorer and Edge */
    scrollbar-width: none;  /* Firefox */
}

}

注意：上面的方法只会删除滚动条的可见性，但它仍然可以正常工作。如果您想删除滚动功能，则可以使用以下选项：

container {
  overflow-y: hidden; /* Hide vertical scrollbar */
  overflow-x: hidden; /* Hide horizontal scrollbar */
}

只需编写以下代码：

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

Or

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

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>

只需将其添加到CSS文件中：

"&::-webkit-scrollbar": {
  display: "none",
  width: 0
},
"-ms-oveflow-style": "none" /* Internet Explorer and Edge */,
"scrollbar-width": "none" /* Firefox */,

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

除了“溢出”之外，你写的所有内容都是正确的。适用于Chrome和其他浏览器的webkit

overflow-y: scroll;

or

overflow-y: auto;

对于Firefox和Edge

scrollbar-width: none;

or

scrollbar-width: thin;
