Is background-size: cover the same as background-size: 100%; ?

In the video [Background: Size and Position], the background-size: cover was introduced and I am just wondering if it is the same as background-size: 100% ? Of course I did tested both and the site looks the same but it may be different on other screen.

Thank you!

background-size: 100%;

The image will fill entire width of the parent container, but not height. Aspect ratio will stay the same

background-size: cover;

It will zoom in to fill the parent container. Some of the image will be cut off

Using "cover" will preserve the aspect ratio, but "100%" will not. Unless the aspect ratio just happens to be the same as the space, "100%" will distort it to fit.

But "cover" will magnify and crop, preserving the aspect ratio but cutting off a bit of the image to do so.
