Note that if you want to use multiple background images, as with the other background properties, you can separate
multiple background-clip properties with a comma.

In Figure 5-19, you may have noticed the newsletter icon disappeared. With a declaration of background-clip:
content-box , the icon was positioned outside the content area and got clipped. background-origin allows
you to change the background positioning area.
In Figure 5-20, I changed the background-clip back to border-box and gave it a background-posi-
tion of 92% 0 . As you can see, the newsletter icon still sits 92% to the right of the box but starts perfectly where
the padding box does—the default value for background-origin .

background-position of 92% 0.
When you change the background-origin to border-box , the newsletter icon touches the top of the border,
as shown in Figure 5-21.

Can you guess what happens when background-origin: content-box is applied? The position of the
newsletter icon starts within the content area, as shown in Figure 5-22.
