This plugin modifies the Additional CSS panel in the theme customizer by adding a button to toggle the CSS editor into fullscreen mode. It is designed for site administrators and developers who frequently write custom styles and want a larger, more focused workspace without leaving the native interface.

• Fullscreen CSS Editor: Click the added maximize icon to expand the CSS editor to fill your entire screen, providing a larger area for writing and reviewing code.
• Native Browser Function: Uses the browser's built-in requestFullscreen API for a standard, reliable fullscreen experience that can be exited by pressing the ESC key.
• Simple Integration: The plugin works by extending the existing theme customizer interface; installation is straightforward and does not require configuration.
• Distraction-Free Editing: The fullscreen mode hides other interface elements, allowing you to concentrate solely on writing and editing your CSS rules.
• Dynamic Button Placement: The maximize button is generated and positioned automatically within the Additional CSS panel, ensuring compatibility with different admin themes and setups.
