如何给scrollLeft变化的元素添加动画效果呢？-灵析社区
正确计算方式如何给scrollLeft变化的元素添加动画效果呢 如题，我想在scrollLeft发生赋值改变的时候给元素加一个动画效果，让移动不那么生硬。
ApplePro给滚动容器设置 "scroll-behavior" (https://link.segmentfault.com/?enc=L7I%2FfG%2Bh8lyq4aQp162hkQ%3D%3D.wK1EbhyXh4wVwPfiKWpcEO%2F0YwI0OFrl%2FERmeTXfgB%2Bo%2BhMerseXIJDSn%2F9%2FuhbXAO3b4Td35fhjq5%2BjxiRQPXyF59WozhWKKeHmhnZzjxE%3D)
属性做平滑滚动？
Click the button to slide right!
Slide right
#container {
width: 100px;
height: 100px;
border: 1px solid #ccc;
overflow-x: scroll;
scroll-behavior: smooth;
}
#content {
width: 250px;
background-color: #ccc;
}
const button = document.getElementById("slide");
button.onclick = function () {
document.getElementById("container").scrollLeft += 20;
};
