WYSIWYG (What You See Is What You Get) Editor is a rich text editor system to help your user to edit the content in a format that resembles its appearance when published.
Just like text editors, WYSIWYG editors are designed to give users the opportunity to write content in a visual way, which means that the user can visually see what he will get once he publishes his content. The more advanced rich text editors also offer editing options such as adding links and images.
Using a rich text editor is a crucial part of creating great user experience for your site. Not all web developers like working with HTML and prefer WYSIWYG editors instead. Rich text controls help to create nice looking things like buttons, input fields and navigation menus without the need to write any code.
