css - 动画 SVG 来回填充

经过 odd issue片刻之前,我继续使用 SVG 进行 CSS 动画实验,但现在,关于着色。

我最初的想法是直接在 <g> 上应用动画规则标签分组所有 <path> ,希望它能“自动”工作。是的,对...

在说服自己我真的需要直接在 <path> 上定义规则之后在里面,我想我必须玩弄时间,所以第一个形状会以一种颜色开始,然后逐渐消失到第二个的开始颜色。然后第二个形状将以第一个形状的颜色结束,模拟来回效果。

这里:

body,
html {
height: 100%;
}

main {
flex: 1 1 auto;
}

.box {
max-height: 600px;
max-width: 600px;
padding: 10px;
}

svg {
height: 100%;
width: 100%;
}

svg path {
fill: #0f68e0;
}

.left {
transform-origin: 190px 555px;
animation: spin-reverse 4000ms linear infinite;
animation-delay: 0.8s;
}

.left path {
animation: colorize-left 6s linear infinite;
animation-delay: 4s;
}

.right {
transform-origin: 605px 555px;
animation: spin-reverse 4000ms linear infinite;
animation-delay: 0.8s;
}

.right path {
animation: colorize-right 8s linear infinite;
animation-delay: 6s;
}

@keyframes spin {
100% {
-moz-transform: rotate(360deg);
-webkit-transform: rotate(360deg);
transform: rotate(360deg);
}
}

@keyframes spin-reverse {
100% {
-moz-transform: rotate(-360deg);
-webkit-transform: rotate(-360deg);
transform: rotate(-360deg);
}
}

@keyframes colorize-left {
0% {
fill: #0f68e0;
}

100% {
fill: #1998ea;
}
}

@keyframes colorize-right {
0% {
fill: #1998ea;
}

100% {
fill: #0f68e0;
}
}

但我显然失败了,因为过渡并不像预期的那样顺利。有人可以帮我吗?

Note: If needed, a small explanation would be nice because this SVG is just a fragment of the real thing, meaning more shapes will participate this timed transition

最佳答案

你差不多好了,问题是动画的最后一个状态与第一个不同,因为你把动画设为 infinite 你会有一个跳跃。

避免这种情况的一个想法是使动画交替。您还需要制作具有相同持续时间的两个动画,并仅向一个元素添加延迟。
