A CMS (Content Management System) website is a site built using software that enables non-technical users to create, manage, modify, and publish digital content without writing code from scratch. Popular platforms like WordPress, Shopify, and Drupal supply intuitive administrative dashboards, WYSIWYG editors, plugin marketplaces, and template repositories. These tools manage databases behind the scenes, allowing teams to seamlessly update blog posts, manage e-commerce product catalogs, and alter site layouts.
