Demonstrating background-repeat

Apatosaurus was a tremendously large long-necked quadrupedal animal with a long whip-like tail. One measurement places the total length of Apatosaurus at 26 meters (85 ft) and its weight at 24-32 tons, roughly the weight of four elephants.

When you position a background image, background-origin allows you to specify your starting point. The default padding-box positions the background image relative to the outer edge of the padding (inner edge of the border), whereas border-box positions the background image relative to the outer edge of the border. There is also the value content-box which, not surprisingly, positions the background image relative to the outer edge of the content (inner edge of the padding).

Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13 ft) tall at the hips.
