A rich text editori is a place to enter content, where you can see the content as it will appear. Basically, all of the HTML code that is used to make the text look the way it does is hidden, unless you click the "HTML" button within the editor to see the raw code. You may simply type plain text into the editor, or you may use the various buttons available at the top of the editor to enhance your text, create links, create tables, or enter images or smiley faces.
