<style type="text/css">.box1{overflow: hidden;width: 800px;height: 500px;padding: 50px;margin: 40px auto;background-color: #32cde8;}.box2{width: 450px;height: 400px;background-color: #2bd09f;float: left;}.box3{width: 200px;height: 400px;padding: 10px;background-color: #71e385;float: left;margin-left: 10px;overflow: hidden;}.box4{width: 50px;height: 50px;background-color: #c377d5;float: left;margin-right: 10px;}.box5{width: 50px;height: 50px;background-color: #597ce5;float: left;margin-right: 10px;}.box6{width: 50px;height: 50px;background-color: #dde773;float: left;}.box7{width: 50px;height: 50px;background-color: #e0a36e;float: left;margin: 10px 10px 0 0;}.box8{width: 50px;height: 50px;background-color: #e556b3;float: left;margin: 10px 10px 0 0;}.box9{width: 50px;height: 50px;background-color: #ea6262;float: left;margin-top: 10px;}</style>六个小盒子下面有一点空，再加一个盒子来存放文本
