What is Gutenberg Page Builder?

Launched as the default block editor in WordPress 5.0, Gutenberg represents a fundamental shift in how content is created and managed within WordPress. Unlike the classic editor, which used a single content area, Gutenberg introduces content blocks—individual units for adding text, images, videos, buttons, and other elements to a post or page. Each block can be customized and moved around, making the process of creating layouts intuitive and flexible.

While Gutenberg was initially designed for page and post content, it’s increasingly being used to create custom WordPress themes by providing developers with the ability to build fully customizable layouts, structures, and elements within their themes.
