在不中断 CSS 的情况下使图像水平滚动无限

Question

我正在尝试制作一个以无限方式水平滚动的徽标组合轮播。

我几乎完成了，但它会破坏动画并且不是无缝的。我需要它真的是一个没有间断的无限动画。

Answer 1

我不太了解宽度 250vw 设置。尝试用 width: fit-content 替换它。然后 -50% 翻译会将图像翻译到正确的位置。

[我假设如果您要显示不同的图像，您知道将它们的完整副本全部放入 HTML 中，这样 -50% 就可以了]。

body {
  margin: 0;
}

.scroll {
  position: relative;
  width: 100vw;
  background-color: $boxify-bg-light-dark;
  overflow: hidden;
  z-index: 1;
  margin: 0;
  padding: 0;
}

.m-scroll {
  overflow: hidden;
  height: 100%;
  white-space: nowrap;
  animation: scrollText 10s infinite linear;
  margin: 0;
  font-size: 0;
  display: flex;
  justify-content: space-between;
  width: fit-content;
}

span {
  display: inline-block;
  margin: 0;
  padding: 0;
  color: white;
}

@keyframes scrollText {
  from {
    transform: translateX(0%);
  }
  to {
    transform: translateX(-50%);
  }
}

Answer 2

我相信用这个替换你的关键帧会起作用，只需写下你的图像的 (width * -1) 而不是我的评论

@keyframes scrollText {
  0% {
    transform: translate3d(0, 0, 0);
 }
  100% {
    transform: translate3d(/* Your image width */, 0, 0); 
 }
}
