How Do I Create a Plain HTML File?
To create a plain html file where you can insert whatever code you would like, proceed to the Create File Page (as explained above). Once you reach that page, you will be sent to a page with a large text box for you to enter your text or HTML code in. Once you are done making your file, type the file name that you wish to save the file as and click "Save Changes" to make the file which can later be edited, renamed and deleted.
