在现代浏览器上，您可以使用wheel事件：

// Content is the element you want to apply the wheel scroll effect to
content.addEventListener('wheel', function(e) {
    const step = 100; // How many pixels to scroll

    if (e.deltaY > 0) // Scroll down
        content.scrollTop += step;
    else // Scroll up
        content.scrollTop -= step;
});

要隐藏内容溢出的元素的滚动条，请使用。

.div{

  scrollbar-width: none; /* The most elegant way for Firefox */
}

只需使用以下三行，您的问题就会得到解决：

#liaddshapes::-webkit-scrollbar {
    width: 0 !important;
}

其中liaddshapes是要滚动的div的名称。

.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;

我加了这个，它对我有用

-ms溢出样式：无；/*IE和Edge*/滚动条宽度：无；/*Firefox浏览器*/

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;
}
