header文件引用了跟多通用模板，所以整个文章会很长，现在比较忙，注释工作会不定期进行
首先开下门户首页的文件
portal里面的index.htm
<!--{template common/header}--> //引用common文件下的header.htm这个也是引用模板文件的一种常用方法
<style id="diy_style" type="text/css"></style> //没什么用
<div class="wp">
<!--[diy=diy1]--><div id="diy1" class="area"></div><!--[/diy]--> //自定义diy框架，前台如果哪个地方需要自定义一个，就添加一个这样的，注意黄字，添加就该一下
</div>
<script src="misc.php?mod=diyhelp&action=get&type=index&diy=yes&r={echo random(4)}" type="text/javascript"></script>
//应该是和diy有关，但是在首页貌似没什么用
<!--{template common/footer}--> //引用common文件下的foot.htm这个也是引用模板文件的一种常用方法 footer这个文件以后在说，这个也很重要
common文件下的header_开头的几个文件
header.htm
<!--{subtemplate common/header_common}--> 引用头部信息 meta什么的也很重要，他会生产一个js和默认的css
<meta name="application-name" content="$_G[‘setting‘][‘bbname‘]" /> //获取可以参看我discuz分类的文章有一篇discuz全局数组变量 后台各项设置 完整版
<meta name="msapplication-tooltip" content="$_G[‘setting‘][‘bbname‘]" />
