Highlight Your Code Syntax with Style Prism .js


Prism.js is a JavaScript library that makes code snippets on websites look great by highlighting their syntax. Whether you're a blogger, developer, or just someone who wants to share code online, Prism.js can help make your code more readable and visually appealing. In this article, we'll break down the steps to use Prism.js and optimize your code.

What is prism.js?

Prism.js is a small, lightweight library that works with a variety of programming languages and markup formats. Add color and formatting to blocks of code, making them easier to read and understand. Prism.js is open source, which means anyone can use it for free.

Getting started with Prism.JS:

To start using Prism.js, you need to add the necessary CSS and JavaScript files to your website. You can download these files from the Prism.js website or use a content delivery network (CDN) link. Including these files ensures that Prism.js works correctly on your site.

Implementing syntax highlighting:

Once you've got Prism.js set up, you can start highlighting your code snippets. To do this, you must define code blocks in your HTML with specific classes that correspond to the programming language you are using. Prism.js will automatically apply the appropriate styling and colors to your code.

Appearance customization:

Prism.js offers several options to customize the appearance of your highlighted code. You can change the color, and font style, and even add line numbers. There are pre-made themes available, or you can create your own custom theme to match your website design.

Supported languages:

Prism.js supports a wide range of programming languages, including JavaScript, HTML, CSS, Python, and more. You can easily find the names of the language classes used for syntax highlighting in the Prism.js documentation.

Performance Considerations:

While Prism.js is powerful, it's important to consider performance. If you have a lot of large code snippets or lots of code blocks on a single page, it can slow down your website. To optimize performance, you can minimize the use of Prism.js on pages where it's not needed, or use lazy loading techniques to load it only when needed.

Beyond the basics:

Prism.js can do so much more! Additional plugins and integrations are available that extend its functionality. For example, you can integrate Prism.js with markdown editors or content management systems (CMS) to seamlessly highlight code in your blog posts or website content.


Prism.js is a great tool for making your code snippets look professional and visually appealing. By following the steps outlined in this beginner's guide, you can easily add syntax highlighting to your website and share your code clearly.
