【原创】增加了单独显示代码的功能
思良：但是显示时很卡，打算有发代码时手动输入算了。
效果如下：
<style type="text/css">
.containersky{padding-right:15px;padding-left:15px;margin-right:auto;margin-left:auto}
.colsky-md-8{position:relative;min-height:1px;padding-right:10px;padding-left:10px;float:left;width:66.66666667%}
.containersky pre{ border:0; width:0; height:0; background:none;}
.syntaxhighlighter {max-height: 271px;}
</style>
<link rel="stylesheet" type="text/css" href="/skin/skyzsyone/css/shCore.css">
<div class="containersky">
<div class="colsky-md-8">
<pre name="code" class="brush: html;">
具体代码内容</pre></div></div>
<script type="text/javascript" src="/skin/skyzsyone/js/XRegExp.js"></script>
<script type="text/javascript" src="/skin/skyzsyone/js/shCore2.js"></script>
<script type="text/javascript" src="/skin/skyzsyone/js/shBrushXml.js"></script>
<script type="text/javascript">
SyntaxHighlighter.all()
</script>
