用google prettify code给blogspot代码着色
Wordpress有许多代码语法高亮插件可以便捷地展示源代码，但是Blogspot我还发现此类的应用。不过我们可以让google prettify code为Blogspot着色代码。
google prettify code是一个轻量级的Javascript模块通过CSS文件对代码进行上色处理，支持C、Java、PHP、Python、HTMLl和Javascript等十几种语言。让我们动手吧。
1.进入Blogspot控制台 –>布局 –>修改HTML
在head区调用google prettify code的Javascript和CSS文件：
<link href="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css" rel="stylesheet" type="text/css"/> <script src="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js" type="text/javascript"/>
2.将“<body>”改成“<body onload=’prettyPrint()’>”
3.修改pre标签的CSS以适合您的使用。
pre { margin: 5px 20px; border: 1px dashed #666; padding: 5px; background: #f8f8f8; white-space: pre-wrap; /* css-3 */ white-space: -moz-pre-wrap; /* Mozilla, since 1999 */ white-space: -pre-wrap; /* Opera 4-6 */ white-space: -o-pre-wrap; /* Opera 7 */ word-wrap: break-word; /* Internet Explorer 5.5+ */ }
现在可以写一篇博客试一下了，将您的代码放在pre标签内，给pre加上class为“prettyprint”，即：
<pre class=”prettyprint”>
your code
</pre>
您可以访问我在blogspot上的博客查看效果。
如果代码是HTML，建议将它们转换成postable后再写入文章，不过如果用ScribeFire写作，它会将代码自动转换成postable，ScribeFire真得不错。下面两个网站可以在线转换：

I modified this for you.
