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;
}

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;
}

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

这是一个类似于divitis的解决方案，所有浏览器都可以使用它。。。

标记如下所示，需要位于具有相对定位的内部（其宽度应设置为400像素）：

<div class="hide-scrollbar">
    <div class="scrollbar">
        <div class="scrollbar-inner">

        </div>
    </div>
</div>

CSS：

.hide-scrollbar {
    overflow: hidden;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
}

.scrollbar {
    overflow-y: scroll;
    position: absolute;
    top: 0;
    left: 0;
    right: -50px;
    bottom: 0;
}

.scrollbar-inner {
    width: 400px;
}

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 */
}

HTML格式：

<div class="parent">
    <div class="child">
    </div>
</div>

CSS:

.parent{
    position: relative;
    width: 300px;
    height: 150px;
    border: 1px solid black;
    overflow: hidden;
}

.child {
    height: 150px;   
    width: 318px;
    overflow-y: scroll;
}

相应地应用CSS。

在这里检查（在Internet Explorer和Firefox中测试）。
