A headless CMS (content management system) has no built-in front-end functionality and instead, it provides an API (application programming interface) for developers to access the content and display it on the front-end using their own code. This means that the front-end can be built using any language, framework, or platform that can connect to the API, making it more flexible and decoupled from the CMS.
The term "headless" comes from the fact that the CMS has no "head" (i.e. no built-in front-end) and instead, it focuses on providing an API for managing the content.
Headless CMSs are becoming increasingly popular because they allow for more flexibility and scalability, as the front-end can be built using any technology, separate from the CMS. This also enables the use of multiple front-end channels like web, mobile, smart devices, and even voice assistants. It also allows for better performance and personalization, as the front-end can be optimized for specific devices or contexts without being constrained by the CMS.
This is different from traditional or monolithic CMSs, which usually have a built-in front-end that is tightly integrated with the content management functionality. This can make it more difficult to customize the front-end or to use multiple front-end channels.
In a headless CMS, the backend and the frontend are connected, but they’re connected by an application programming interface (API) instead.
Please keep in mind that Headless CMSs are not the best solution for all use cases, it is especially useful for those who want more flexibility and scalability in their web or mobile application and also for those who want to create personalized experiences.

Example: Ghost, a headless CMS
This blog is build on Ghost. Ghost is an open-source, node.js based headless CMS that is designed to be easy to use, customizable and efficient.
Ghost allows users to create, manage and organize content using its built-in editor, and it exposes the content through a RESTful API, which can be consumed by any front-end technology or framework. Ghost also uses markdown for formatting and it has built-in SEO features.
Headless CMSs like Ghost allow developers to decouple the content management system from the front-end presentation layer, which can be beneficial in many situations. It can increase development speed, improve scalability, and make it easier to create personalized, dynamic and responsive user experiences.
In my case I can decide to change the full layout and design directly.
