CSS 动画翻转时钟

Question

i have a problem when making Flip Clock animation

the animation will perform like this reference

reference : http://hilios.github.io/jQuery.countdown/

so far, this is my work.

demo : https://jsfiddle.net/s3qk25m7/1

i try this one :

HTML :

<div class="time">
  <span class="count top flipTop">2</span>
    <span class="count top">1</span>
    <span class="count bottom flipBottom">1</span>
  <span class="count bottom">2</span>
</div>

CSS :

.time {position: relative; height: 95px; width: 65px;
  perspective: 200px; backface-visibility: hidden;
  transform: translateZ(0); transform: translate3d(0,0,0);
}
.count {background: #202020; color: #f8f8f8; display: block;
  font-size: 2em; line-height: 2.4em; overflow: hidden;
  position: absolute; text-align: center;
  top: 0; width: 100%;
}
.top {height: 50%; line-height:95px; transform-origin: 50% 100%; }
.bottom {line-height: 0; height: 50%; top: 50%; transform-origin: 50% 0; }

@keyframes flipTop {
  from {
      transform: rotateX(0deg);
  }
  to {
      transform: rotateX(-90deg);
  }
}
@keyframes flipBottom {
    from {
        transform: rotateX(90deg);
    }
    to {
        transform: rotateX(0deg);
    }
}

.flipTop {
    animation-name: flipTop;
    animation-duration: 0.25s;
    animation-fill-mode: both;
}
.flipBottom {
    animation-name: flipBottom;
    animation-duration: 0.25s;
     animation-delay: 0.25s;
    animation-fill-mode: both;
}

the animation not working properly. how to solve this issue?

what's wrong with my code?

thanks in advance...

Answer 1

The issue is that the animated div is behind the static.

To fix this add z-index: 1 to your .flipPosition class.

Check out this updated fiddle

Edit: note that the lower div's number seems to be updated too early

Edit 2: I just realized that ngAnimateSwap would probably be perfect for this!
