[Full-screen Demo](https://rawgit.com/bahrus/in-the-node/master/demo/index.html) Provide the initial notebook script via a child script tag: ```html ``` ## Syntax color JS object / JSON Run-kit also comes with a nice prebuilt JSON syntax colorizer / tree view. To support this basic functionality, pass the object you want to format to the input property: ```JavaScript document.querySelector('in-the-node').input = {myStringProp: 'hello', mySubObjProp:{greeting: 'hello'}} ``` ## Install the Polymer-CLI First, make sure you have the [Polymer CLI](https://www.npmjs.com/package/polymer-cli) and npm (packaged with [Node.js](https://nodejs.org)) installed. Run `npm install` to install your element's dependencies, then run `polymer serve` to serve your element locally. ## Viewing Your Element ``` $ polymer serve ```
