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;
}

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;
}

.your-overflow-scroll-class::-webkit-scrollbar {
  ...
  width: 0.5rem; //only hide the vertical scrollbar
  height: 0px; //only hide the horizontal scrollbar
}

Use

function reloadScrollBars() {
    document.documentElement.style.overflow = 'auto';  // Firefox, Chrome
    document.body.scroll = "yes"; // Internet Explorer only
}

function unloadScrollBars() {
    document.documentElement.style.overflow = 'hidden';  // firefox, chrome
    document.body.scroll = "no"; // Internet Explorer only
}

对于您想要加载、卸载或重新加载滚动条的任何点，调用这些函数。当我在Chrome中测试它时，它仍然可以在Chrome中滚动，但我不确定其他浏览器。

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 */,
