Code Block – share beautiful code snippets readers can copy vs Syntax-highlighting Code Block (with Server-side Rendering)

Turn plain code into beautifully highlighted, copy-ready snippets your readers will love – right inside the Gutenberg editor. Code Snippets Block | Pricing | Support | Live Demos What Is Code Snippets Block? Code Snippets Block is a lightweight WordPress code block plugin for displaying programming code with syntax highlighting, copy-to-clipboard functionality, responsive layouts, and multiple visual themes. Add clean and readable code examples to WordPress posts, pages, documentation, tutorials, developer portfolios, knowledge bases, and technical websites without writing custom code. The plugin works directly with the WordPress Gutenberg Block Editor and supports popular programming languages including PHP, JavaScript, Python, HTML, CSS, JSON, and SQL. Why Use Code Snippets Block? Publishing code in a normal text editor can make technical content difficult to read and copy. Code Snippets Block turns your code into a structured, highlighted, and copy-ready code block. It is useful for developers, technical writers, educators, bloggers, documentation creators, agencies, and anyone publishing programming content with WordPress. Free Features One-Click Copy Button: Readers copy the entire snippet to their clipboard in a single click, with customizable text/icon. Multiple Syntax Themes: Choose from pre-styled themes (like Dark, Midnight, and Light) to match your website design. Syntax Highlighting: Improve readability for all major languages – PHP, JavaScript, Python, HTML, CSS, and more. Responsive Code Views: Snippets wrap and resize smoothly on mobile, tablet, and desktop. Shortcode Support: Embed code snippets anywhere on your site. Dedicated Block Category: All blocks are grouped under a “Code” category in the Gutenberg inserter for easy access.

This plugin extends the Code block in WordPress core to add syntax highlighting which is rendered on the server. Pre-existing Code blocks on a site are automatically extended to include syntax highlighting. Doing server-side syntax highlighting eliminates the need to enqueue any JavaScript on the frontend (e.g. Highlight.js or Prism.js) and this ensures there is no flash of unhighlighted code (FOUC?). Reducing script on the frontend improves frontend performance, and it also allows for the syntax highlighted code to appear properly in AMP pages as rendered by the official AMP plugin (see also ampproject/amp-wp#972) or when JavaScript is turned off in the browser. This extended Code block uses language auto-detection to add syntax highlighting, but you can override the language in the block’s settings sidebar. (There is currently no syntax highlighting of the Code block in the editor, but see #8.) The plugin supports all programming languages that highlight.php supports (being a port of highlight.js). The Code block also is extended to support specifying lines to highlight which get marked up with mark elements (including in RSS feeds). There is also a checkbox for whether to show line numbers on the frontend (with the numbers being non-selectable). Lastly, given inconsistencies across themes regarding whether lines in a Code block should be wrapped, this plugin adds styling to force them to no-wrap by default, with a checkbox to opt in to wrapping when desired.
