WYSIWYG is an abbreviation for "What You See Is What You Get" and refers to a software function that allows users to edit and format content on the screen in the way they want it to look later.

WYSIWYG allows users to easily format and edit content without the need for programming skills. Most word processing programmes, content management systems and website builders use WYSIWYG editors to enable users to easily edit and format content.

WYSIWYG editors allow users to format text by selecting fonts, colours, sizes and styles, inserting images and videos, creating tables and lists and adding links. The text is usually displayed on the screen in the same way as it will later appear on the website or in the document.

WYSIWYG editors are a useful feature for users who want to create or edit content without having extensive programming knowledge. WYSIWYG allows them to format and edit content quickly and easily without having to worry about the technical details. This also facilitates collaboration between different users, as they can make changes to a document in real time and see how it will look on the website or in the document.

Overall, WYSIWYG is an important function in software development that enables users to create and edit content quickly and easily without the need for extensive programming skills.
