纯CSS实现隐藏滚动条但仍具有滚动的效果（移动端和pc端）

  .container::-webkit-scrollbar {
    display: none;
  }

<div class="outer">
    <div class="content">
      <p>1111</p>
      <p>222</p>
      <p>333</p>
      <p>444</p>
    </div>
</div>
 .outer {
   width: 300px;
   height: 300px;
   overflow: hidden;
 
   .content {
     width: 330px;
     /*margin-right: -15px;*/
     height: 100%;
     overflow-x: hidden;
     overflow-y: auto;
     background: red;
     padding-top: 100px;
 
     p:not(:first-child) {
       margin-top: 100px;
     }
   }
 }
