JSFiddle

Sometimes when working on a website, you have an idea for how a cool new feature should work but you can't figure out how to code it. But someone else has probably figured it out, right? And yes, when you go on Google to look for the answer, you'll likely be taken to StackOverflow, where you'll probably then be linked to a JSFiddle - basically proof that their answer is right, because they got the idea working!

This is primarily for testing website features, using HTML, CSS and/or JavaScript. It is a very flexible playground as well for testing out something that you have in mind without having to go through the overhead of making new files somewhere on your system then forgetting where they are later.

Some cool fiddles made by smart people (not me):
