浮动的同级盒子顶对齐

情景：四个盒子如下图布局，使用浮动，可以看到3和4是顶对齐的

<body>
    <div class="w">
        <div class="box1">1</div>
        <div class="box2">2</div>
        <div class="box3">3</div>
        <div class="box4">4</div>
    </div>
</body>
<style>
        .w{
            width: 1000px;
            margin: 0 auto;
        }
        .box1{
            background: rgb(226, 23, 23);
            height: 200px;
            width: 300px;
            float: left;
        }
        .box2{
            background: #008000;
            height: 100px;
            width: 400px;
            float: left;
        }
        .box3{
            background:#0000ff;
            height: 100px;
            width: 400px;
            float: left;
        }
        .box4{
            background: #000000;
            width: 300px;
            height: 50px;
            float: right;
            color: #ffebcd;
        }
    </style>

此时会看到出现bug，4盒子上不去，解决方法是把4盒子放到2盒子和3盒子中间

 <div class="w">
        <div class="box1">1</div>
        <div class="box2">2</div>
        <div class="box4">4</div>
        <div class="box3">3</div>
    </div>
