只需编写以下代码：

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

Or

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

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;
}

以下Sass样式应使滚动条在大多数浏览器上透明（不支持Firefox）：

.hide-scrollbar {
  scrollbar-width: thin;
  scrollbar-color: transparent transparent;

  &::-webkit-scrollbar {
    width: 1px;
  }

  &::-webkit-scrollbar-track {
    background: transparent;
  }

  &::-webkit-scrollbar-thumb {
    background-color: transparent;
  }
}

这对我有用

div {
  -ms-overflow-style: none; /* Edge, Internet Explorer */
  scrollbar-width: none; /* Firefox */
  overflow-y: scroll;
}

// hides scrollbars while allowing to scroll
div::-webkit-scrollbar {
  display: none; /* Chrome, Safari, Opera */
}

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>

scrollbar-width: none; 

为我工作。
