Syntax Highlighting on Blogspot

Using highlightjs

• Go to https://highlightjs.org/download/ to check for the latest version
• Or insert the following tags at the end of the body tag of your theme

<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.13.1/styles/default.min.css"/>
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.13.1/highlight.min.js"></script>
<script>hljs.initHighlightingOnLoad();</script>

• You can choose another highlighting theme like listed at https://github.com/highlightjs/highlight.js/tree/master/src/styles
• Just change the linked css file from default.min.css to whateverthemeyoulike.min.css

Using Google Prettify

• Also a nice alternative to highlightjs is google prettify 
• Using it is as easy as adding the js file to your HTML Template
  

  <script src='https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js?autoload=true&skin=sons-of-obsidian'></script>

• And put you code into
  

   <pre class="prettyprint linenums lang-html">
    <code>
  YOUR CODE
    </code> 
   </pre>
  

• You can choose other styles from the skin gallary and add your choice as parameter to the url &skin=sons-of-obsidia
