`Frequently Asked Questions`



How does syntax highlighting work?


The plugin uses the powerful Highlight.js library to automatically find and highlight code within standard WordPress “Code” blocks. There’s no need to look for a special block; just use the default one, and the plugin handles the rest.


Which programming languages are supported?


The plugin supports: JavaScript, CSS, PHP, Python, Bash/Shell, SQL, Java, C++, C, C#, Ruby, Go, Rust, TypeScript, JSON, YAML, XML, HTML, Docker, Nginx, and plain text. Auto-detection is also available.


How many themes are available?


The plugin includes over 80 themes, including popular ones like GitHub, Monokai, Atom One, and many more. All themes are available in both light and dark variants.


Does this work with caching plugins?


Yes, the plugin works well with caching plugins and can complement them by ensuring proper asset loading and syntax highlighting even with cached content.


Can I customize the appearance?


Yes! Go to Settings > Syntax Highlighter to choose from over 80 different color themes using a visual theme selector. The copy-on-double-click feature is enabled by default.


Does it work with page builders?


Yes, the plugin should work with any page builder that uses the standard WordPress “Code” block. For other cases, you might need to use a custom HTML block and wrap your code in <pre><code class="language-yourlanguage">...</code></pre>.


How do I highlight specific lines?


Line highlighting is not currently supported. This feature may be added in future updates.


Is the plugin lightweight?


Yes! The plugin only loads its scripts and styles on pages that actually contain a code block, making it very performant.
