javascript - 取消选中复选框 css3 动画

Question

当我的复选框被选中时我有一个动画，但我想在它们未被选中时反转动画。我尝试了伪类 :unchecked，但我发现它不起作用。是否有 CSS3 方法或可能是一个小的 jQuery 修复？

@import url(https://fonts.googleapis.com/css?family=Open+Sans:400,600,700);
@keyframes checked {
  0% {
    tranform: scale(1);
  }
  50% {
    transform: scale(1.05);
  }
  100% {
    transform: scale(1);
  }
}

  box-sizing: border-box;
