Make a Syntax Highlighter on Blogger

Table of Contents

Syntax Highlighter is an additional feature on blogs that allows writing program code to look like editor code.

This feature is almost the same as blockquote, but when we write something in blockquote, the style will look the same as writing articles in general.

This Syntax Highlighter also gives a more attractive appearance to your blog. Immediately, we proceed to the tutorial article below.

Placement of CSS and Scripts

1. Go to your blogger dashboard. Then click Themes. At the top right there are 3 vertical dots, click and select > Edit HTML.

Next. The Edit HTML theme for your blog will appear. Continue to step two.

2. Copy the code below.

<!-- Syntax highlighter -->
<style type='text/css'>
/* Highlighter */
pre{white-space:pre;word-wrap:normal;overflow:auto;font-size:14px;margin:0;padding:0}hr{margin-top:2rem;background:#ccc;height:1px;border:0;margin-bottom:2rem}
.post-body code{padding:1.2em}.post-body pre{padding:0;border-radius:3px;background-color:#292e34;word-spacing:normal;word-break:normal;line-height:1.4em}.post-body .hljs{display:block;overflow-x:auto;padding:1.2em;background:#2b2b2c;color:#fff;line-height:1.5;text-align:left;word-spacing:0;font-family:monospace;border-radius:3px}.post-body .hljs-name,.post-body .hljs-strong{font-weight:bold}.post-body .hljs-code,.post-body .hljs-emphasis{font-style:italic}.post-body .hljs-tag{color:#62c8f3}.post-body .hljs-variable,.post-body .hljs-template-variable,.post-body .hljs-selector-id,.post-body .hljs-selector-class{color:#ade5fc}.post-body .hljs-string,.post-body .hljs-bullet{color:#a2fca2}.post-body .hljs-type,.post-body .hljs-title,.post-body .hljs-section,.post-body .hljs-attribute,.post-body .hljs-quote,.post-body .hljs-built_in,.post-body .hljs-builtin-name{color:#ffa}.post-body .hljs-number,.post-body .hljs-symbol,.post-body .hljs-bullet{color:#d36363}.post-body .hljs-keyword,.post-body .hljs-selector-tag,.post-body .hljs-literal{color:#fcc28c}.post-body .hljs-comment,.post-body .hljs-deletion,.post-body .hljs-code{color:#888}.post-body .hljs-regexp,.post-body .hljs-link{color:#c6b4f0}.post-body .hljs-meta{color:#fc9b9b}.post-body .hljs-deletion{background-color:#fc9b9b;color:#333}.post-body .hljs-addition{background-color:#a2fca2;color:#333}.post-body .hljs a{color:inherit}.post-body .hljs a:focus,.post-body .hljs a:hover{color:inherit;text-decoration:underline}mark .post-body .hljs-attr,mark .post-body .hljs-string,mark .post-body .hljs-bullet{background-color:#e67e22;color:#fff}.post-body .hljs mark{background-color:#f24a4a;color:#fff;padding:2px 5px;border-radius:2px}.post-body .hljs mark span.hljs-number,.post-body .hljs mark span.hljs-comment,.post-body .hljs mark span.hljs-symbol,.post-body .hljs mark span.hljs-string,.post-body .hljs mark span.hljs-attr,.post-body .hljs mark span.hljs-keyword,.post-body .hljs mark span.hljs-name,.post-body .hljs mark span.hljs-tag{color:#fff;margin:.15rem 0}
</style>

• Put the code above just above the tag code </head> or &lt;/head&gt;&lt;!--<head/>--&gt;

An easy way to find HTML editor tags on blogger, use CTRL+F to speed up the search.

3. Copy the code below, place it just above the code tag </body>.

<!-- Syntax highlighter -->
<script type='text/javascript'>
//<![CDATA[
// Highlighter
$('i[rel="pre"]').replaceWith(function(){return $("<pre><code>"+$(this).html()+"</code></pre>")});for(var pres=document.querySelectorAll("pre,code,kbd,blockquote,td"),i=0;i<pres.length;i++)pres[i].addEventListener("dblclick",function(){var e=getSelection(),t=document.createRange();t.selectNodeContents(this),e.removeAllRanges(),e.addRange(t)},!1);
function downloadJSAtOnload(){var e=document.createElement("script");e.src="https://cdn.jsdelivr.net/gh/Arlina-Design/frame@master/highlightr.js",document.body.appendChild(e)}window.addEventListener?window.addEventListener("load",downloadJSAtOnload,!1):window.attachEvent?window.attachEvent("onload",downloadJSAtOnload):window.onload=downloadJSAtOnload;
//]]>
</script>

Make sure your theme already has a jquery script library like the following:

<script async='async' src='https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js' type='text/javascript'/>

If you have applied all the steps above, click save.

Writing Program Code in Syntax Highlighter

1. Parse the program you are going to write.
2. Copy the code that you parsed earlier. In general, the code that has been parsed contains code like the following <pre><code>...</code></pre>

<pre><code>
paste disini code yang sudah diparse
</code></pre>

That's a tutorial on how to make a syntax highlighter on Blogger. Good luck.
