How can I hide jsFiddle panels?

I'd like to show pure JavaScript examples in jsFiddle, and I only need a JavaScript window and a console. I've figured out how to get a console window to appear, but is there a way to remove the HTML and CSS windows? Is there a better service than jsFiddle to use for my needs?

How do I fullscreen JSFiddle?

Right-Click the result window in Jsfiddle. Select "This Frame" Select "Show Only This Frame" Page will reload with result only in full screen (without a "run this fiddle" banner in it.)

What does the tidy button do in JSFiddle?

You can press the Tidy button on the top panel at any time and align all the lines automatically.

As of December 4th, 2016 hiding and showing panels was set as an accepted idea in jsfiddle's development roadmap. As of today that's as far as it's got so you'd need to use something else like jsbin or codepen. Maybe give it an upvote in their roadmap to put some pressure on ;)
