        color: white;
        display: flex;
        padding-left: 10px;
        align-items:center;//垂直居中布局

            width: 60px;
            height: 50px;

        }
        .center{
            flex: 1;
            height: 34px;
            line-height: 34px;
            background-color: rgba(255,255,255,0.5);
            text-align: center;
            border-radius: 17px;
            .text{
                font-size: 16px;
            }
        }
        .iconwode{
            font-size: 24px;
        }
        .iconnew{
            font-size: 50px;
        }
    }
</style>

总结

1.采用flex布局,让三个div垂直居中布局。
