Levels Block Editor Styles for Oxygen Builder

Levels Block Editor Styles for Oxygen Builder automatically injects your Oxygen Builder CSS into the WordPress block editor, ensuring that what you see in the editor matches what appears on the frontend.

Features

• Automatic Style Detection – Automatically finds and loads all relevant Oxygen CSS files
• Scoped Styling – All CSS is scoped to prevent affecting editor UI elements
• Reusable Block Support – Detects and loads styles for embedded reusable blocks
• Smart Context Detection – Only loads in the block editor for users with edit permissions
• Performance Optimized – Live-read approach with minimal overhead

How It Works

The plugin collects CSS from four sources:

1. oxygen.css – Core Oxygen framework styles
2. universal.css – Site-wide Oxygen styles
3. Page-specific CSS – Cached page styles
4. Reusable block CSS – Styles for embedded reusable blocks

All CSS selectors are automatically rewritten to be scoped within the editor content area to prevent affecting the WordPress admin UI.

Requirements

• Oxygen Builder 4.x (must be installed and activated)
• WordPress 5.8 or higher
• PHP 7.4 or higher
