我想在一個html 上面生成好多小方塊,結果與百度圖片那種相似，方塊大小是相同的，
（1） 實現的方法 就是設置 div 的float 屬性就可以了 left
div { background-color:Gray; width:150px; height:150px; float:left; margin:10px;}
（2）怎么讓div 的文字顯示在div 的中央
text-align:center; line-height:150px;text-align:center;(水平居中)line-height:和高一樣的參數;(垂直居中)，
（3）怎么讓div 顯示在頁面的特定部位
<div style='position:absolute;top:20%;left:15%;z-index:9; width:800px; height:600px'></div>
（4） 使用jiathis 分享
<script type="text/javascript" src="http://v3.jiathis.com/code/jiathis_r.js?uid=1356925732494226&move=0" charset="utf-8"></script>
將這句話加入到body 里面就行了
