When WordPress introduced Full Site Editing (FSE) with block themes, the familiar “Additional CSS” option was moved from the Customizer to the Site Editor’s Styles panel. This plugin brings back easy access by adding an “Additional CSS” link directly to the Appearance menu.
Features:
<ul>
<li>Adds “Additional CSS” link under Appearance menu</li>
<li>One-click access to the Site Editor CSS panel</li>
<li>Only appears when using a block theme</li>
<li>Lightweight and simple – no settings needed</li>
<li>Works with any block theme</li>
</ul>
How It Works:
Simply activate the plugin and you’ll see “Additional CSS” appear in your Appearance menu. Clicking it takes you directly to the CSS editing panel in the Site Editor.
