如何合理地为 Font Awesome 锁定图标设置动画

Question

我想知道如何在以某种智能方式切换/动画它们的同时将Font Awesome Lock Icon 和Font Awesome Lock Open Icon 交织在一起。例如有this flip animation。

<script src="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta2/js/all.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta2/css/all.min.css" rel="stylesheet"/>
<div class="fa-5x">
  <i class="fas fa-lock fa-flip" style="--fa-animation-duration: 10s; color: red"></i>
  <i class="fas fa-unlock fa-flip" style="--fa-animation-duration: 10s; color: green"></i>
</div>

例如，现在叠加两个图标是有意义的，将一个设置为display: none，然后在单击或悬停时切换它们。但是如何在动画时间的一半之后切换它们，以便在各个图标只能从侧面看到一条线的那一刻进行交换？或者您对合理的动画有更好的想法？

Answer 1

您不能为两个不同的图标设置动画以获取unlock effect。但是，如果不是很重要，您可以创建自己的 svg 图标和动画。

const icon = document.getElementById('icon');
icon.addEventListener('click', () => {
  icon.classList.toggle('green');
});

const icon2 = document.getElementById('icon2');
icon2.addEventListener('click', () => {
  icon2.classList.toggle('green');
})

*,
::after,
::before {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

:root {
  --bg: hsl(201, 27%, 10%);
}

body {
  height: 100vh;
  background: var(--bg);
  display: flex;
  justify-content: center;
  align-items:center;
  gap: 1em;
  position: relative;
}

#icon,
#icon2 {
  width: 52px;
  height: auto;
  position: relative;
  cursor: pointer;
}

#icon rect,
#icon path,
#icon2 path {
  transition: all 0.5s ease-in-out;
}

#icon rect {
  fill: red;
}
#icon2 path#body {
fill: red;
}

#icon path,
#icon2 path#hook {
  stroke: red;
  stroke-dasharray: 30;
  stroke-dashoffset: 5;
  fill: none;
}

#icon.green rect,
#icon2.green path#body {
  fill: green;
}

#icon.green path,
#icon2.green path#hook {
  stroke: green;
  stroke-dasharray: 20;
}

/* keyhole */

#keyhole {
  width: 10px;
  height: 16px;
  border-radius: 25px;
  position: absolute;
  top: 65%;
  left: 50%;
  background-color: var(--bg);
  transform: translate(-50%, -50%) rotate(0deg);
  transition: all 0.5s ease-in-out;
  z-index: 1;
}

#icon.green #keyhole {
  transform: translate(-50%, -50%) rotate(-180deg);
}
