Let's go ahead and grab a cool picture to use as a background. Go [here](http://atelierkarim.com/assets/grfx/site/backgrounds/upfeathers.png) and save the image in your `4-assets` folder, with the rest of your resources. ## Sample Code Let's add this sample code to your `background.html` file: ```markup Backgrounds

Background

You can set the background of your webpage to a simple color, or you can use an image. The background you set can be for the entire page and/or certain divs.

``` ## CSS Sample Code Let's add this sample code to your `background.css` file: ```css .wrapper{ margin: 5px; } /* 3 */ h1{ text-align: center; } /*this sets the background color of the entire body*/ body{ background-color: lightgray; } /* 4 */ .background1{ background-color: lightblue; } /* 5 */ .background2{ background-image:url("../4-assets/upfeathers.png"); } /* 7 */ table, th, td{ border: 1px solid black; } ``` ## Discussion Much like fonts, backgrounds are another aspect of an application that can make or break the user experience. You can see that implementing `background` isn't as challenging as many other properties, however, consider carefully what the result will be. Neutral colors, grayscales and blurred backgrounds tend to be more accessible to the average user.
It's important to note how the file path works here: `../4-assets/upfeathers.png`. When we use `../`, that means back up one level from the current directory, then, go look for the `4-assets` folder. Inside there, look for `upfeathers.png`. If we wanted to look two directories above, we could say `../../`. ## Challenge Find an image you like, and try using it as a `background`. Explore other options like [gradients](https://www.w3schools.com/css/css3_gradients.asp) as backgrounds.
