<ol>
<li><strong>Gutenberg Block Editor</strong>: Use the default WordPress “Code” block. The plugin automatically detects the language and highlights it.

If you need to force a language, edit the block as HTML and add a class to the <code><code></code> element (e.g., <code><code class="language-php"></code>).</li>
<li><strong>Classic Editor</strong>: Use the TinyMCE button (code icon) with the modal dialog for easy code insertion.</li>
<li><strong>Copy to Clipboard</strong>: Double-click any code block to instantly copy its content with visual feedback.</li>
</ol>
