我有一个高度和宽度有限的 div，其内容超出了 div 的大小。所以我在 div 的顶部和底部放置了两个图像，我希望内容相对于我悬停的图像上下滚动。我已经设法悬停但它不受控制，即使我将鼠标从图像上移开，它也会一直持续到最后。因此，当我将鼠标移开时，我希望滚动停止，并且当我再次将鼠标悬停在图像上时，我希望滚动从停止的位置恢复。 jsfiddle

The Mauritius Blue Pigeon is an extinct species of blue pigeon formerly endemic to the Mascarene island of Mauritius in the Indian Ocean east of Madagascar. It has two extinct relatives from the Mascarenes and three extant ones from other islands. It had white hackles around the head, neck and breast and blue plumage on the body, and it was red on the tail and the bare parts of the head. These colours were thought similar to those of the Dutch flag, a resemblance reflected in some of the bird's names. It was 30 cm (12 in) long and larger and more robust than any other blue pigeon species. It could raise its hackles into a ruff, which it used for display. Its call sounded like "barf barf" and it also made a cooing noise. It fed on fruits, nuts, and molluscs, and was once widespread in the forests of Mauritius. The bird was first mentioned in the 17th century and was described several times thereafter, but very few accounts describe the behaviour of living specimens. Several stuffed and at least one live specimen reached Europe in the 1700s and 1800s. Only three stuffed specimens exist today, and only one bird was ever depicted when alive. The species is thought to have become extinct in the 1830s due to deforestation and predation. (Full article...)
