A content management system (CMS for short) is software that is used to create and manage content - in text, image, video or other form. CMS are mainly used to operate websites, but also for "offline platforms" (in intranet networks). Open source systems are particularly widespread and are used by both professional and private users. Especially for content-rich websites such as online shops or media portals, implementation with the help of finely-tuned CMS is a good idea.
Designers support their clients in choosing the right CMS and create the front and back-end design of the CMS, if necessary using existing themes, so that clients can create and manage their content efficiently and effectively.
