10 Free Syntax Highlighter WordPress Plugins

One of the really great aspects of the web design community is their willingness to share solutions and ideas. As such, many people choose to post tutorials and helpful code snippets on their blogs.

When viewing code, it’s a good idea to make the snippets look as clean and easy to read as possible. You’ll also want to make sure it’s easy for users to copy and paste for their own use.

In addition to posting snippets on the front end, there are also some good reasons to add syntax highlighting within WordPress itself. First, the standard WordPress code editor can be cumbersome when trying to find a specific code — especially on longer pages and posts.

Here is a collection of free WordPress plugins to help you beautifully view and edit your code.

Designed for use with both block and classic editors, Highlight Code Block makes viewing your highlighted code in syntax easy. Many popular languages ​​are supported, and a built-in settings screen allows you to customize the display.

With Prism’s syntax highlighter, Code Syntax Block improves on existing Code block. This makes it easy to view rich code snippets on the front end without any extra work.

In addition, the plugin includes a selection of visual themes. Additional options are available through the Prism Theme Repository.

Code Block was created to highlight grammar with a focus on performance. Install the plugin and it will automatically add language highlighting to your WordPress Code block – including existing blocks.

Since it shows the server side of the code, there is no need to queue JavaScript in the front end of your site. CSS is only added on pages that contain the code block. It is also compatible with Google AMP.
