The default Additional CSS editor in Gutenberg feels like writing code in Notepad. It’s small, lacks structure, and makes debugging a headache.
This plugin transforms that basic textarea into a comfortable, lightweight CSS editor directly inside the Site Editor.
My greatest wish is that this plugin will become obsolete once WordPress includes this feature natively in Gutenberg. Until then, it substantially improves your daily workflow.
Key coding features supported:
<ul>
<li>Line numbers</li>
<li>Auto indented</li>
<li>Auto closing parenthesis</li>
<li>Add comments with Ctrl / Cmd shortcodes (Ctrl + Ç, Ctrl + / and Ctrl + 7)</li>
</ul>
