定义 dom,容器中包含 5 个子元素:
居中显示:
body { margin: 0; height: 100vh; display: flex; align-items: center; justify-content: center; background-color: black;}
定义均衡器的样式:
.equalizer { width: 10em; height: 10em; display: flex; justify-content: space-between;}
.equalizer span {
width: 1.5em; background: linear-gradient(0deg, green, yellow, red); }定义均衡器竖条的动画效果:
.equalizer span { animation: up-and-down 2s linear infinite;}
@keyframes up-and-down{
0%, 100% { clip-path: inset(27% 0 0 0); }10% { clip-path: inset(17% 0 0 0);}20% { clip-path: inset(55% 0 0 0);}30% { clip-path: inset(30% 0 0 0);}40% { clip-path: inset(13% 0 0 0);}50% { clip-path: inset(38% 0 0 0);}60% { clip-path: inset(80% 0 0 0);}70% { clip-path: inset(21% 0 0 0);}80% { clip-path: inset(0% 0 0 0);}90% { clip-path: inset(36% 0 0 0);}
}
最后,设置各竖条依次动画:
.equalizer span { animation: up-and-down 2s linear infinite calc(-1 * 0.4s * (var(--n) - 1));}
.equalizer span:nth-child(1) {
–n: 1; }.equalizer span:nth-child(2) {
–n: 2; }.equalizer span:nth-child(3) {
–n: 3; }.equalizer span:nth-child(4) {
–n: 4; }.equalizer span:nth-child(5) {
–n: 5; }大功告成!
