使用 SVG 的关键帧动画

Question

我正在尝试制作动画CSS，其中我有一个"代码"和"计算机屏幕"的SVG文件。

我试图实现的是当我的代码在最后翻译时，我不想在我的无限循环上有空屏幕。我想让代码一直移动。我试图通过划分代码并使其中一个代码循环更快来做到这一点(这就是为什么你可以看到我有 code1、code2 和 code3 类(。不幸的是，这对我来说也失败了。

有人可以给我建议或想法如何做到这一点吗？

在这里，您可以看到JSFiddle上的示例

.animation {
	height: 124px;
	width: 180px;
	overflow: hidden;
}
@keyframes scrolling1 {
	0% {
		transform: translateY(0);
	}
	100% {
		transform: translateY(-370px);
	}
}
.code1,
.code2,
.code3 {
	animation: scrolling1 4s linear infinite;
}
/* collors */
.st0 {
	opacity: 0.17;
}
.st1 {
	fill: #56aeec;
}
.st2 {
	fill: #2c65cc;

.st3 {

Answer 1

为了达到你想要的效果，我建议将移动内容(内部svg(分解成几个部分。

如果它被分解成几个部分，它们可以一个接一个地在屏幕上滑动。一旦每个部分离开屏幕，它就可以返回到其原始位置，在可见区域底部下方，并准备再次在屏幕上滑动。

我以此为例，说明如何实现内容无休止滚动的效果：https://codepen.io/samcole/pen/ePLErz

.HTML：

<div class="outer">
<div class="inner inner--1">
</div>
<div class="inner inner--2">
</div>
<div class="inner inner--3">
</div>
</div>

.CSS：

.outer {
width: 200px;
height: 200px;
background: black;
overflow: hidden;
position: relative;
}
.inner {
width: 200px;
height: 200px;
position: absolute;
animation: scroll;
top: 200px;
left: 0;
animation: scroll 6s linear infinite;
}
.inner--1 {
background: red;
}
.inner--2 {
background: green;
animation-delay: 2s;
}
.inner--3 {
background: blue;
animation-delay: 4s;
}
@keyframes scroll {
0% {
top: 200px; 
}
100% {
top: -400px;
}
}

Answer 2

保持HTML/SVG不变，但偏移动画开始时间，以便最上面的图像(.code1(回到底部位置：

<style>
.animation {
height: 124px;
width: 180px;
overflow: hidden;
}
@keyframes scrolling1 {
0% {
}
70% {
transform: translateY(-410px);
}
100% {
transform: translateY(-410px);
}
}
@keyframes scrolling2 {
0% {
}
70% {
transform: translateY(-324px);
}
100% {
transform: translateY(-324px);
}
}
@keyframes scrolling3 {
0% {
}
70% {
transform: translateY(-226px);
}
100% {
transform: translateY(-226px);
}
}
.code1 {
animation: scrolling1 4s linear infinite;
animation-delay: 0s;
transform: translateY(-190px);
}
.code2 {
animation: scrolling2 4s linear infinite;
animation-delay: 1.3333s;
transform: translateY(-104px);
}
.code3 {
animation: scrolling3 4s linear infinite;
animation-delay: 2.6666s;
transform: translateY(-6px);
}
