<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        *{
            padding: 0;
            margin: 0;
        }
        #left,#right{
           width: 200px;
            height: 100px;
            background-color: red;
        }
        #left{
            float: left;
        }
        #right{
            float: right;
        }
        #center{
            height: 100px;
            background: yellow;
        }
    </style>

<body>
<div id="box">
