先到範本>編輯HTML
在<head></head>之間插入：
<script src='https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js?lang=css&skin=sunburst'/>
儲存
不知為何上面的連結過幾天就沒效果了，可以試試看下面，是我從官網抓的，後來換這就可以了：
<script defer='defer' src='https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js?autoload=true&lang=css&lang=ml&skin=sunburst'/>
再到範本>自訂>進階>新增CSS
插入這段：
.prettyprint.linenums ol li,
pre.prettyprint.linenums ol li {//這是讓每行程式都顯示行號
list-style: decimal;
}
.post .prettyprint { //設定程式碼區塊
overflow-x:auto;
overflow-y:auto;
max-height:800px;//max-height設定區塊高度
white-space:pre;//保留原始空白與換行
}
現在只要在pre tag裡插入程式碼即可：
<pre class="prettyprint linenums">
code.................
</pre>
原本上面程式區塊我做不出來，這時就要把特殊符號轉碼了，請到這個網站，像<>這樣的特殊符號就要轉碼，轉出來再放到pre tag裡，像上面如果我要顯示<pre class="prettyprint linenums">怎麼做？你想，很簡單，就一樣插到pre tag，不就變成pre tag裡還有一個pre tag？我試過，這樣不行，所以才要轉碼。參考資料：
