Introduction
This is just a basic "fun" tag and serves little practical purpose on it's own. Enclosing text in this allows the viewer to "edit" whataver text is enclosed. Don't worry, the change is not permanent! :-)

Basic Code:
Very simple enclose the text in these tags:

<div contenteditable="true">Enclosed text here.</div>

Result: Anywhere on this page you can delete or add text. I have added

It isnt much use nor does it serve any particular purpose, but it is fun! Note, that images are editable etc. and this may make some of the page disproportionate.
