css - 如何给一个元素添加两种动画样式

Question

我正在处理这个 CSS 片段。为什么我无法将脉冲和淡出动画 Angular 色添加到跨度中？

从技术上讲，我喜欢将两者都放在一个动画中，或者启用同时接受脉冲和淡出动画

html,body {
   height:100%;
   width:100%;

}
#point {
   height:100%;
   width:100%;
position:relative;
}


.pulse {
  position:absolute;
  margin:30px;
  display: block;
  width: 22px;
  height: 22px;
  border-radius: 50%;
  background: #cca92c;
  cursor: pointer;
  box-shadow: 0 0 0 rgba(204,169,44, 0.4);
  animation: pulse 2s infinite;
}
.pulse:hover {
  animation: none;
}

@-webkit-keyframes pulse {
  0% {
    -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -webkit-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -webkit-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
@keyframes pulse {
  0% {
    -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
    box-shadow: 0 0 0 0 rgba(204,169,44, 0.4);
  }
  70% {
      -moz-box-shadow: 0 0 0 10px rgba(204,169,44, 0);
      box-shadow: 0 0 0 10px rgba(204,169,44, 0);
  }
  100% {
      -moz-box-shadow: 0 0 0 0 rgba(204,169,44, 0);
      box-shadow: 0 0 0 0 rgba(204,169,44, 0);
  }
}
.hideMe {
  -webkit-animation: seconds 1.0s forwards;
  -webkit-animation-iteration-count: 1;
  -webkit-animation-delay: 5s;
  animation: seconds 1.0s forwards;
  animation-iteration-count: 1;
  animation-delay: 5s;
 
}
@-webkit-keyframes seconds {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
    left: -9999px; 
  }
}
@keyframes seconds {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
    left: -9999px; 
  }
}

<span class="pulse hideMe"></span>

.dot {
  position: absolute;
  margin: 30px;
  display: block;
  width: 22px;
  height: 22px;
  border-radius: 50%;
  background: #cca92c;
  cursor: pointer;
  box-shadow: 0 0 0 rgba(204, 169, 44, 0.4);
  opacity: 1;
}

.dot--animation {
  animation:  pulse 2s infinite,
              hide .3s forwards 5s;
}
.dot--animation:hover {
  animation: none;
}

@keyframes pulse {
  0% {
    -moz-box-shadow: 0 0 0 0 rgba(204, 169, 44, 0.4);
    box-shadow: 0 0 0 0 rgba(204, 169, 44, 0.4);
  }
  70% {
    -moz-box-shadow: 0 0 0 10px rgba(204, 169, 44, 0);
    box-shadow: 0 0 0 10px rgba(204, 169, 44, 0);
  }
  100% {
    -moz-box-shadow: 0 0 0 0 rgba(204, 169, 44, 0);
    box-shadow: 0 0 0 0 rgba(204, 169, 44, 0);
  }
}

@keyframes hide {
  100% {
    opacity: 0;
  }
}

<div class="dot dot--animation"></div>
