Background Images in CSS

The background properties are

background-color, which is used to specify the color for background
background-image, which is the location of the image itself.
background-repeat, which is how the image repeats itself. This can be repeat (equivalent to a 'tile' effect across the whole background), repeat-y (repeating on the 'y-axis', above and below), repeat-x (repeating on the 'x-axis', side-by-side) or no-repeat (which shows just one instance of the image).
background-position, which can be top, center, bottom, left, right or any sensible combination, such as above.
