Background Image
The background of a div doesn't have to just be a color, it can also be an image. Simply define the url of the image and it will be set as the background of the div. The image address can be the url of the online location of the image or the file path if the image is on your computer. Notice that the image address needs to be enclosed in quotation marks and parenthesis. In order to properly adjust the size of the image to fit nicely within the div, use the background-size property and give it the value of cover. Try entering different image addresses and setting the background-size to cover to see the effect.
There are other background properties in addition to the image address and background-cover. Most of those are used less frequently so you don't need to know them now. However, the background-repeat property may be used fairly often. If the image is smaller than the div and can't fill it completely then it will repeat. You have the option of setting this property to repeat (which is the default) or no-repeat.
