                margin: 20px auto;
                padding: 20px;

            }
            .box div{
                width: 80px;
                height: 80px;
                float: left;
            }
            .clearfloat::after{
                content: '';
                clear: both;
                display: block;
            }
        </style>
    </head>
    <body>
        <div class="box">
            <div ></div>
            <div ></div>
            <div ></div>
        </div>
    </body>
</html>

1：给父元素加上display: flex
2：给父元素加上overflow: auto||hidden
3：给父元素加上名为clearfloat的class
以上三种方法均可达到消除浮动的效果
