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;
}

这对我有用：

scroll-content {
    overflow-x: hidden;
    overflow-y: scroll;
}

scroll-content::-webkit-scrollbar {
    width: 0;
}

我知道这是一个非常古老的问题，但这里有一个仅使用HTML和CSS的跨浏览器解决方案。

HTML格式：

  <div class="barrel">
    <div class="clipper">
        <p class="clippercontent">Lorem</p>
    </div>
    <div id='navcontainer'>
      <p class="navcontent" >I want to be able to scroll through the whole page, but without the scrollbar being shown. Is there a way I can remove the scrollbar while still being able to scroll the whole page? With just CSS or HTML, please.
     </p>
    </div>
  </div>

原则：#navcontainer将容纳我们的.navcontent，并将有滚动条。barrel将隐藏#navcontainer的滚动条。

CSS:

.barrel{
  border: 0.8px solid #110011;
  position: relative;
  overflow: hidden;
}
.barrel #navcontainer{
  overflow: scroll; overflow-y: hidden;
  position: absolute;/* absolute positioned contents will not affect their parents */
  top: 0; left: 0; right: 0;
  white-space: nowrap;
}
/* style .clipper and .clippercontent, as a structural-image of #navcontainer and .navcontent respectively This will help .barrel have the same height as the #navcontainer */
.barrel .clipper{
  overflow: hidden;
  width: 0px;
  white-space: nowrap;
}
.navcontent, .clippercontent{
  padding: 3px 1px;
}

只需将子对象的宽度设置为100%，将填充设置为15像素，将overflow-x设置为滚动和溢出：为父对象隐藏，并设置您想要的宽度。

它适用于所有主要浏览器，包括Internet Explorer和Edge，但Internet Explorer 8及更低版本除外。

.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;

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;
  }
}
