CSS实现文本两端对齐

<el-col :span="3"><span class="newFix-name">车牌号：</span></el-col>
<el-col :span="3"><span class="newFix-name">基础信息：</span></el-col>
<el-col :span="3"><span class="newFix-name">车型信息：</span></el-col>

<style scoped>
    .newFix-Info-box li span {
        display: inline-block;
        width:70px;
        height:30px;
        color: #999;
        margin-right: 10px;
        text-align: justify;
        vertical-align: middle;
      }
      .newFix-Info-box li span:after{
        display: inline-block;
        width:100%;
        height: 0;
        content: '';
      }
</style>
