## Beskrivelse

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:

 * Line numbers
 * Auto indented
 * Auto closing parenthesis
 * Add comments with Ctrl / Cmd shortcodes (**Ctrl + Ç**, **Ctrl + /** and **Ctrl
   + 7**)

## Installation

## FAQ

### Does this plugin require Gutenberg?

Yes, Advanced editor for Additional CSS only works with new FSE experience / Gutenberg.
If you use the old Customizer editor, these features are included by default. Gutenberg
plugin is not needed.

### Will I lose my current CSS changes if I enable/disable this plugin?

No, Advanced editor for Additional CSS recognizes the Additional CSS content and
just replaces the textarea behavior.

### Does this plugin affect my website’s front-end performance?

No, not at all. This plugin only loads its scripts and styles within the WordPress
admin area (specifically inside the Site Editor). It does not add a single byte 
of code to the front-end, keeping your website’s loading speed and Core Web Vitals
completely unaffected.

### Does it support CSS property autocomplete or Emmet?

Currently, the plugin focuses on enhancing the editor’s core structure (line numbers,
auto-indentation, and shortcuts). Full property autocompletion is not included in
this version, but it helps keep the plugin incredibly lightweight and fast.
