The WYSIWYG (What You See Is What You Get) concept is present in almost every content creation or update action performed over the web. The WYSIWYG principle implies that in the final form, the published version, the content will have a similar structure and appearance with the one obtained during the editing process.
Modern web applications and sites have implemented WYSIWYG editors as necessary functionality both for users (in case of comments or feedback forms, forums posts and more) and administrators who update or add content to a website with the help of online visual tools. For example, almost all content management systems provide in administration control panel a WYSIWYG HTML editor or the possibility to add one as plug-in.
WYSYWYG editors allow persons that do not have technical skills to add or edit website content in a visual manner because they automatically generate the necessary HTML code to reflect certain user actions, like changing the text heading, adding or resizing an image, inserting audio or video files in web pages and more. The web based WYSIWYG editors are widely used because they require only a browser to run and allow users to perform website content modification online, without the need to use supplementary FTP programs or to install third party applications.
