Question

我正在尝试创建一个等待/倒数屏幕，以显示眼睛和眼睑以及带有虹膜效果的眼球。考虑到我们中的许多人都花了很多时间无聊地盯着这些微调器，我要实现的效果是“眼睛”微调器回头看着观众并眨眼。

document.getElementById('waitDia').showModal();

var ticks = 300,
    ticker = setInterval(changeTick,1000);

function changeTick()
{
 document.getElementById('spnTick').innerText = --ticks;
 if (0 === ticks) clearInterval(ticker);
}

#waitDia
{
 position:absolute;
 left:0 !important;
 top:0 !important;
 width:100vw !important;
 height:100vh !important; 
 padding:0; 
 min-width:100vw;
 min-height:100vh; 
 background-color:transparent !important;
}

#waitDia::backdrop{background-color:rgba(127,127,127,0.2);}

#spnTick
{
 position:absolute;
 display:inline-block;
 width:100%;
 left:0;
 top:0;
} 
#waitbox
{
 left:0 !important;
 top:0 !important;
 width:100vw !important;
 height:100vh !important;
 position:absolute;
 overflow:hidden;
}


#eyeball
{
 position:relative;
 top:-10vh;
 left:-6px;
 width:calc(24vh + 12px);
 height:calc(24vh + 12px);
 box-sizing:border-box;
 background:rgba(0,128,128,0.5);
 border-radius:100%;
 border:1px solid transparent;
 box-shadow:inset 0 0 18px 2px blue;
 z-index:99999998;
}


#waitsecs
{
 position:absolute;
 left:calc(50vw - 12vh);
 top:46vh;
 width:24vh;
 height:24vh;
 font-size:8vh;
 text-align:center;
 display:block;
 
}

#waitEye
{
 position:absolute;
 top:27vh;
 left:calc(50vw - 23vh);
 width: 46vh;
 height: 46vh;
 background-color: rgba(255,255,255,.9);
 border-radius: 100% 0px;
 transform: rotate(45deg); 
 mix-blend-mode:overlay;

}

<dialog id='waitDia' class='waitdia'>
   <div id='waitbox'>
    <div id='waitsecs'><span id='spnTick'>300</span><div id='eyeball'></div></div>
   <div id='waitEye'></div> 
   </div>  
  </dialog>

到目前为止，我已经实现的目标如下所示-我在这里仅将代码设置为300秒，以使代码持续运行很短的时间-在实际应用中，等待时间很可能是小得多。

虽然这种效果朝着正确的方向发展，但仍然缺乏眼睑眨眼效果。我怀疑，借助正确的“盒子阴影”操作和简单的动画，这很容易实现。但是，在这里，我达到了兼职CSS技能的极限。非常感谢在座的任何人，他们有可能提出改进建议以完成此实现。

Answer 1

我会以不同的方式进行操作，并考虑旋转以获得眨眼效果。诀窍是用两个元素（眼睑）使眼睛眨眼。

这是只有眨眼动画的代码：

.eye {
  width: 250px;
  height: 80px;
  margin: 50px;
  display:inline-block;
  perspective: 200px;
  background:
    radial-gradient(circle 100px at 50% 250%,#f1c27d 99% ,transparent 100%) top/100% 50%,
    radial-gradient(circle 100px at 50% -150%,#f1c27d 99% ,transparent 100%) bottom/100% 50%;
  background-repeat:no-repeat
}

.eye>div {
  height: 50%;
  position:relative;
  overflow:hidden;
  transform-origin:bottom;
  animation:b1 0.8s  infinite ease-out alternate;
}
.eye>div:last-child {
  transform-origin:top;
  animation-name:b2;
}
.eye>div:before {
  content: "";
  position: absolute;
  top:0;
  left:10%;
  right:10%;
  padding-top:80%;
  border-radius:50%;
  background:#fff;
  box-shadow:
    -2px 0 0 3px inset #f1c27d,
    inset -5px 5px 2px 4px black;
}
.eye>div:last-child:before {
  bottom:0;
  top:auto;
  box-shadow:
    -2px 0 0 3px inset #f1c27d,
    inset -6px -4px 2px 4px black;
}


body {
 background:#000;
}

@keyframes b1{
  to { transform:rotateX(-88deg);}
}
@keyframes b2{
  to {transform:rotateX(88deg);}
}

<div class="eye">
  <div></div>
  <div></div>
</div>

这是一个更加真实的眨眼动作：

var ticks = 300,ticker;
setTimeout(function() { ticker = setInterval(changeTick,1600);},500);

function changeTick()
{
 document.querySelector('.eye span').setAttribute('data-text', --ticks);
 if (0 === ticks) clearInterval(ticker);
}

.eye {
  width: 250px;
  height: 80px;
  margin: 50px;
  display:inline-block;
  perspective: 200px;
  background:
    radial-gradient(circle 100px at 50% 250%,#f1c27d 99% ,transparent 100%) top/100% 50%,
    radial-gradient(circle 100px at 50% -150%,#f1c27d 99% ,transparent 100%) bottom/100% 50%;
  background-repeat:no-repeat;
  transform-style:preserve-3d;
  position:relative;
}

.eye>div {
  height: 50%;
  position:relative;
  overflow:hidden;
  transform-origin:bottom;
  z-index:1;
  animation:b1 0.8s  infinite ease-out alternate;
}
.eye>div:last-child {
  transform-origin:top;
  animation:none;
}
.eye>div:before {
  content: "";
  position: absolute;
  top:0;
  left:10%;
  right:10%;
  padding-top:80%;
  border-radius:50%;
  background:#fff;
  box-shadow:
    -2px 0 0 3px inset #f1c27d,
    inset -5px 5px 2px 4px black;
  animation:inherit;
  animation-name:color;
}
.eye>div:last-child:before {
  bottom:0;
  top:auto;
  box-shadow:
    -2px 0 0 3px inset #f1c27d,
    inset -6px -4px 2px 4px black;
}
.eye > span {
  position:absolute;
  width:45px;
  height:45px;
  bottom:18px;
  left:50%;
  transform:translateX(-50%) translateZ(55px);
  overflow:hidden;
  border-radius:20% 20% 0 0;
  z-index:2;
  animation:b2 0.8s  infinite ease-out alternate;
}
.eye > span:before {
  position:absolute;
  left:0;
  bottom:0;
  height:45px;
  width:100%;
  content:attr(data-text);
  border-radius:50%;
  background:#000;
  color:#fff;
  text-align:center;
  line-height:45px;
}


body {
 background:#000;
}

@keyframes b1{
  to { 
    transform:rotateX(-170deg);
  }
}
@keyframes b2{

  }
  40.1%,100% { 
    background:#f1c27d;

Answer 2

SVG解决方案

没有计数器的版本

通过改变眼睑的动画来实现从顶部到底部移动属性“ d”。
获得逼真的眼睑图像（给定体积）径向渐变被使用。
在眼睑的上下位置暂停动画为重复通过positions属性d

主要思想是根据动画帧之间的增量时间，将贝塞尔曲线的两个控制点移动到眼睑的形状，

requestAnimationFrame(draw);

function draw(t) {
  circle.setAttribute('cx', Math.sin(t/1000)*2);
  grad.setAttribute('offset', 40 + Math.sin(t/3000)*20 + '%');
  t = Math.max(0, Math.sin(t/300));
  t = (t<.5 ? 16*t*t*t*t*t : 1+16*(--t)*t*t*t*t)*6-3;
  let d = `-7 0C-2 ${t} 2 ${t} 7 0`;
  mask.setAttribute('d', `M-7 -7${d}L7 -7z`)
  eyelid.setAttribute('d', `M${d}`)
  requestAnimationFrame(draw);
}

具有进度和鼠标移动反应的解决方案

  // процент загрузки
  let r = 1.8, 
      p = progress *2 * Math.PI, 
      px = r*Math.cos(p), 
      py = r*Math.sin(p),
      arc = 1-Math.round(progress);
      
  load.setAttribute('d', `M${r},0 A${r},${r},0,${arc},0,${px},${py}L0,0z`)
  load.setAttribute('transform', `translate(${x}, ${y})`)
  
  // анимируем градиент
  let offset = Math.max(0.2, (0.5 - len/2/innerHeight))*100 + "%";  
  grad1.setAttribute('offset', offset);
  grad2.setAttribute('offset', offset);
  
  // сглаживаем время по формуле easeInOutQuint

  t = (t<.5 ? 16*t*t*t*t*t : 1+16*(--t)*t*t*t*t)*6-3;
