.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;
}

scrollbar-width: none; 

为我工作。

隐藏水平和垂直滚动条。

请在此处查看Fiddle

HTML

 <div id="container1">
    <div id="container2">
    <pre>

Select from left and drag to right to scroll this very long sentence. This should not show scroll bar at bottom or on the side. Keep scrolling .......... ............ .......... ........... This Fiddle demonstrates that scrollbar can be hidden. ..... ..... ..... .....
    </pre>

    </div>
    <div>

CSS

* {
    margin: 0;
}
#container1 {
    height: 50px;
    width: 100%;
    overflow: hidden;
    position: relative;
}
#container2 {
    position: absolute;
    top: 0px;
    bottom: -15px;
    left: 0px;
    right: -15px;
    overflow: auto;
}

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;
});

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。
