    <title>浮动模型</title>
    <style>
        #bodydiv{
            width: 300px;
            height: 300px;
            border: 2px blue dashed;
        }
        #div1,
        #div2,
        #div3{
            width: 300px;
            height: 100px;
        }
        #div1 div{
            width: 100px;
            height: 100px;
            background-color: red;
            margin: 0 auto;
        }
        #div2 div{
            width: 100px;
            height: 100px;
        }
        .div2-1{
            background-color: green;
            float: left;
        }
        .div2-2{
            background-color: yellow;
            float: right;
        }
        #div3 div{
            width: 100px;
            height: 100px;
            background-color: blue;
            margin: 0 auto;
        }


    </style>
</head>
<body>
<div id="bodydiv">
    <div id="div1">
        <div></div>
    </div>
    <div id="div2">

        <div class="div2-1"></div>
        <div class="div2-2"></div>

    </div>
    <div id="div3">
        <div></div>
    </div>

</div>

</body>
</html>

思路分析:
注意布局中的占位和浮动,利用三个div进行占位之后再对div进行浮动

第二种模式:
在div2块中进行设置属性

display: flex;
justify-content: space-between;
