                    <image class="item-icon" src="../../static/login-m.png"></image>  
                    <view class="item-inpt">

data() {  
            return {  
                mobile:'',  
            }  
        },

.login-assembly {  
        margin-top: 40rpx;  
        display: flex;  
        flex-direction: column;  
        justify-content: center;  
        padding: 0 90rpx;  

        .account-item {  
            display: flex;  
            align-items: center;  
            padding: 25rpx 28rpx;  
            z-index: 2;  
            margin-top: 40rpx;  

            .item-icon {  
                width: 36rpx;  
                height: 56rpx;  
            }  
            .item-inpt{  
                display: flex;  
                justify-content: space-between;  
                align-items: center;  
                border-bottom: 1px solid #fff;  
                width: 100%;  
                margin-left: 27rpx;  
            }  
            .item-input {  
                color:#fff;  
                flex: 1;  
                font-size: 28rpx;  
                margin-bottom: 20rpx;  
            }  
        }  
    }
