The main feature of a content management system (CMS) is to provide tools that enable users to create, manage, and modify digital content without extensive technical knowledge. A CMS allows users to easily publish and organize content, such as articles, images, and videos, through intuitive interfaces. Popular CMS platforms like WordPress and Drupal offer customizable templates, plugins, and user management options, making it simple for individuals and organizations to maintain their online presence and keep content fresh and engaging.
