Question: I got a coin flip CSS animation from `[https://www.html5andbeyond.com/coin-flip-application-html-css-and-jquery][1]` but its not working on my page. I tried to confirm by checking on fiddle but its not working there also. However, its working on the provider's website. Here is the fiddle link I created to check. [`https://jsfiddle.net/7q8dqfxy/`](https://jsfiddle.net/7q8dqfxy/) 

Codes are placed as it is on fiddle. Please check for the issue and help me guys.

Answer: 
The JavaScript code here relies on the jQuery library, so you need to include that as an external resource.

In jsFiddle, this can be achieved like this:

In your regular page, you'll want to either bundle jQuery with your HTML page, or include a link via a [CDN](https://code.jquery.com/) like this

```
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>

```
Jquery library is missing.

Insert below line in your code

```
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"> 

```
