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）。

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 */,

另一种黑客方法是执行overflow-y:hidden，然后手动滚动元素，如下所示：

function detectMouseWheelDirection(e) {
  var delta = null, direction = false;
  if (!e) { // If the event is not provided, we get it from the window object
    e = window.event;
  }
  if (e.wheelDelta) { // Will work in most cases
    delta = e.wheelDelta / 60;
  } else if (e.detail) { // Fallback for Firefox
    delta = -e.detail / 2;
  }
  if (delta !== null) {
    direction = delta > 0 ? -200 : 200;
  }
  return direction;
}

if (element.addEventListener) {
  element.addEventListener('DOMMouseScroll', function(e) {
    element.scrollBy({
      top: detectMouseWheelDirection(e),
      left: 0,
      behavior: 'smooth'
    });
  });
}

deepmikoto的博客中有一篇关于如何检测和处理onmousewheel事件的精彩文章。这可能对你有用，但绝对不是一个优雅的解决方案。

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>

以下内容适用于我在Microsoft、Chrome和Mozilla上的特定div元素：

div.rightsidebar {
    overflow-y: auto;
    scrollbar-width: none;
    -ms-overflow-style: none;
}
div.rightsidebar::-webkit-scrollbar { 
    width: 0 !important;
}

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;
}
