Speed-highlight JS is a lighter and faster version of prism that share a similar API
Style
Remove the prism stylesheet in the head of your html file Clone this repository or use a cdn to load our stylesheet
<head>
- <link href="themes/prism.css" rel="stylesheet" />
+ <link rel="stylesheet" href="https://unpkg.com/@speed-highlight/core/dist/themes/default.css">
</head>Script
For the script part remove the prism.js script and replace it by a import and a call to highlightAll
<body>
- <script src="prism.js"></script>
+<script>
+ import { highlightAll } from 'https://unpkg.com/@speed-highlight/core/dist/index.js'
+ highlightAll()
+</script>
</body>If you want to highlight only a specific element you can use the highlightElement function instead
Code block
For the code blocks replace the <pre><code> by only one <div>
And use shj-lang- prefix instead of language- for the class property
-<pre><code class="language-css">p { color: red }</code></pre>
+<div class="shj-lang-css">p { color: red }</div>And for inline code block you just have to change the class property
-<code class="language-css">p { color: red }</code>
+<code class="shj-lang-css">p { color: red }</code>Languages supported 🌐
