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 <code> element (e.g., <code class="language-php">).
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.
