A WYSIWYG editor (What You See Is What You Get) is a type of software that allows users to create and edit content visually, without needing to write code. This means that users can see how their text, images, and other elements will appear on the final page as they work, making it easier for those without technical skills to design web pages or documents. These editors are commonly used in web development and content management systems, such as WordPress or Adobe Dreamweaver. They simplify the process of formatting text, adding multimedia, and arranging layouts, enabling users to focus on creativity rather than technical details.
