是否有必要编写头部、正文和HTML标记？
<html>, <head><body>
<!DOCTYPE html> <meta http-equiv="Content-type" content="text/html; charset=utf-8"> <title>Page Title</title> <link rel="stylesheet" type="text/css" href="css/reset.css"> <script src="js/head_script.js"></script><!-- this script will be in head //--><div>Some html</div> <!-- here body starts //--> <script src="js/body_script.js"></script>
