Lissa's HTML Editor is a handy little editor that should not take the place of you learning regular HTML, but should be a tool to help you get familiar with the way HTML is transfered into a code that a browser can read.
In order to begin using this HTML editor, you need to highlight and delete all the text in this text area.
You can completely format your site in this editor, add images, add tables, and upload the finished product into your own Web host's editor without knowing any HTML.
After you've finished formatting your page in the editor, you would push the < > button, and your html source code will be shown. Copy and paste this code into your own Web host's editor, and upload it to your server.
