The Tryit Editor - very nice indeed!

If you are making your own HTML widgets, like I have started to try to do, then the Tryit Editor is a really helpful way of seeing the result as you are working on it. This is something that is probably already quite well known to others, but I thought I would share it anyway. As is already the case with a lot of other wonderful things, this is brought to us by W3Schools:

So, here is also a screenshot of how it works. You enter your code into the left window, click "Run" at the top and what you are making gets updated on the right window. You cannot save anything, when you are happy with what you have copy paste it into your HTML widget box. And that's it.
