如何合理设置字体锁图标的动画

font-awesome css javascript

Three Year Old · 技术社区 · 4 年前

我想知道怎样才能交织在一起 Font Awesome Lock Icon 和 Font Awesome Lock Open Icon 在切换/设置动画时,它们会以某种方式变得聪明。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,现在可以叠加两个图标,将一个设置为 display: none 然后点击鼠标或鼠标悬停或其他方式切换。但是,如何在动画时间的一半后切换它们,以便在各个图标只能从侧面看到一条线时进行交换?或者你对合理的动画有更好的想法吗?

你不能通过设置两个不同图标的动画来获得 unlock effect 。但是,如果不是关键的,您可以创建自己的svg图标并设置动画。

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;

  border-radius: 25px;
  position: absolute;

  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);
}
