## Description
[Easy Syntax Highlighter](https://www.tiptinker.com/easy-syntax-highlighter-wordpress-plugin/)
is a powerful WordPress plugin that helps improve your website’s code presentation
by providing beautiful syntax highlighting. Using the latest Highlight.js library,
it supports over 20 programming languages with 80+ color themes, copy-to-clipboard
functionality, and seamless integration with both classic and Gutenberg editors.
### Features
* **Modern Highlight.js Engine**: Uses the latest Highlight.js library for fast,
accurate syntax highlighting
* **80+ Themes Included**: Over 80 themes for both light and dark modes, all stored
locally for offline compatibility
* **Unlimited Language Support**: Supports 20+ programming languages including
JavaScript, PHP, Python, CSS, HTML, SQL, Bash, and more
* **Modern JavaScript**: Promise-based loading with proper error handling and performance
optimizations
* **Performance Optimized**: Smart asset loading—only loads when code blocks are
present on the page
* **Security Focused**: Proper input sanitization and output escaping
* **Admin Interface**: Clean, modern settings page with visual theme selector integrated
with WordPress admin
* **Localization Ready**: Translation-ready with proper text domains
* **Backward Compatible**: Automatic migration from old plugin versions
### How to Use
1. **Gutenberg Block Editor**: Use the default WordPress “Code” block. The plugin
automatically detects the language and highlights it. There is no language setting
in the sidebar; detection is automatic. If you need to force a language, edit the
block as HTML and add a class to the `` element (e.g., ``).
2. **Classic Editor**: Use the TinyMCE button (code icon) with the modal dialog for
easy code insertion.
3. **Copy to Clipboard**: Double-click any code block to instantly copy its content
with visual feedback.
### Use Cases
* Technical blogs and tutorials
* Documentation websites
* Programming courses and educational content
* Developer portfolios
* API documentation
* Code examples and snippets

## FAQ
### 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 `...
`.
### 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.
