The “Light Code Block” plugin is a simple and lightweight solution for inserting and displaying code snippets in posts and pages. 
It works by adding a custom “LC” button to the TinyMCE (Classic) editor or a code block in the Gutenberg editor.
The inserted code will be shown on the front end in a clean, readable format.
<h3>Usage</h3>
<ul>
<li>Install and activate the plugin.</li>
<li>Go to the post or page edit screen.</li>
<li>In the TinyMCE (Classic) editor, click the “LC” button in the toolbar.</li>
<li>In the popup window that opens, paste or write your code, and click OK.</li>
<li>Save or update your post.</li>
</ul>
The code will be saved inside a special block and displayed on the front end within a <code><pre></code> tag with the class <code>mce-simple-code-block</code> (i.e., <code><pre class="mce-simple-code-block">...</pre></code>).
To insert code using the Gutenberg editor, you first need to add a Classic (TinyMCE) block, and then use it to insert your code.
