HTML5教程:HTML5的基础写法
对比一下XHTML 1.0 Transitional的规范，html5基本上没有XHTML 1.0 Transitional严格的要求，并且简化了很多东西。
•文档声明更简单了。
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 2 <!--在HTML5中，这样写：--> 3 <!DOCTYPE html>
•html标签上不需要声明命名空间。
1 <html xmlns="http://www.w3.org/1999/xhtml"> 2 <!--在HTML5中，这样写：--> 3 <html>
•字符集编码声明也简单了
1 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 2 <!--在HTML5中，这样写：--> 3 <meta charset="UTF-8" />
•可以不用给css及javascript代码写type属性了
1 <script type="text/javascript"></script> 2 <style type="text/css"></style> 3 <!--在HTML5中，可以直接写：--> 4 <script></script> 5 <style></style>
•没有XHTML代码规范的要求
所有的标记都必须要有一个相应的结束标记；
所有标签的元素和属性的名字都必须使用小写；
所有的XML标记都必须合理嵌套；
所有的属性必须用引号”"括起来；
1 <p></p> 2 <br> 3 <INPUT TYPE="TEXT" /> 4 <!--这些都不做严格要求-->
