<style>
        .showTotal{
          width: 100%;  //must set
          overflow: auto;
        }
        .outter{
          width: 98%;
          min-width: 60vw;
          height: auto;  
          overflow: auto;
          display: flex;
          flex-flow: row nowrap;
          justify-content: flex-start;
          align-items: flex-start;
          margin:0 auto;
          padding-bottom: 30px;  
        }
        .list{
          background: linear-gradient(45deg,#fff7b3 30%,#fffcdd 60%, #fff 90%);
          border: 1px solid #98fae5;
          border-radius: 15px;
          box-shadow: 0 0 6px #98fae5;  
          margin-top:20px;
          padding: 10px 15px 30px 15px;
          flex:1 0 80vw;
          margin-left: 30px;
          height: 70vh;
        }
    </style>

<div class="showTotal">
            <div class="outter">
                <div class="list">
                </div>
                <div class="list">
                </div>
                <div class="list">
                </div>
                <div class="list">
                </div>
                <div class="list">
                </div>
            </div>
        </div>

需要外层套一个div 并设置固定宽度
