/**
* Challenge: get a random image from Unsplash and set it as the background
*
* Part 1:
*
* URL: https://apis.scrimba.com/unsplash/photos/random?orientation=landscape&query=nature
* (You can change the "query" at the end to whatever theme you want)
*
* Change the body's backgroundImage to:
* `url(<insert the URL of the iamge from the API here>)`
*
* (You may need to dig around the response body a bit to find this URL)
*
* (Note I've already added some CSS to resize the image within the window.
* Instructions for this were found on CSS Tricks:
* https://css-tricks.com/perfect-full-page-background-image/#awesome-easy-progressive-css3-way)
