希望优化这种无限滚动效果,但是我不完全确定在循环回原始图像时如何创建平滑过渡。在 10 多岁时几乎不明显,但在 30 多岁时更明显。我假设它与结束头寸 margin 有关,但不能完全确定它。最后一帧的值应该是多少?

最佳答案
看看这个:https://jsfiddle.net/sergdenisov/wb28eeh2/3/ .
您在图像之间有不必要的空间(因为 display: inline
,请阅读这篇文章 — https://css-tricks.com/fighting-the-space-between-inline-block-elements/)。我设置:
.photobanner, .photobanner2 {
font-size: 0
}
然后我删除
padding-right: 2px
并设置:.photobanner img, .photobanner2 img {
margin-right: 5px;
}
2之间的真正空间
img
标签是 6px
,现在是 5px
.现在我们可以计算所需的
margin-left
动画:6 x (350 + 5) = 2130px
.就是这样。
