You can modify the text in the box to the left any way you like, and then click the “Show Page” button below the box to display the result here. Go ahead and do this as often and as long as you like.
When you are satisfied with your page, you can select all text in the textarea and copy it to a new text file, with an extension of either .htm or .html, depending on your Operating System. This file can then be moved to your Web server.
