Advantages of Gutenberg Editor:

1. Block-Based Editing: Gutenberg’s block-based approach allows for more control and flexibility. Each piece of content – be it a paragraph, image, or video – is its own block, making it easier to manipulate and arrange.
2. Modern Interface: With a more modern and cleaner interface, Gutenberg is more user-friendly, especially for those new to WordPress.
3. Enhanced Media Handling: Gutenberg simplifies the process of adding and editing media content, with features like drag-and-drop image uploads and easy image gallery creation.
4. Mobile-Friendly Editing: The editor is optimized for mobile use, making it easy to manage content on the go.
5. Custom Blocks: Developers can create custom blocks, extending the functionality and allowing for more tailored content creation.
6. Reusable Blocks: You can save and reuse blocks across different posts and pages, saving time and maintaining consistency.
7. Content Focus: Gutenberg encourages a more content-focused approach to website building, making it easier for non-technical users to create visually appealing layouts.
