DivCSS小结：浏览器默认HTML的CSS样式属性

　　这个“阅读器默许HTML的CSS 款式属性”，在你需求还原默许值的时候， 比较有用 。开始的时候 利用通配 取舍器 *{margin:0;padding:0;}，当需求 使用边距的时候，就需求还原HTML默许CSS值了 。

　　但通配 取舍器在大型网站的构建中，影响性能， 可以参考52CSS.com的 有关文章，大家还是需求慎重一些 。

　　以往向来在找这份文档，今日 偶尔在w3上看到了 。除了inline和block的定义，重要是要 留神body|h1'h6|blockquote|menu|ul|ol|dd等标签的默许 款式(margin和font-size) 。
