A WYSIWYG editor (What You See Is What You Get) is a type of software that allows users to create and edit content in a way that visually resembles the final output. This means that as you type and format text, add images, or create layouts, you see exactly how it will appear when published, without needing to write any code. These editors are commonly used in web design, document creation, and content management systems. Popular examples include WordPress, Adobe Dreamweaver, and Google Docs. They simplify the editing process, making it accessible for users without technical skills.
