Question

此动画http://jsfiddle.net/ts9AG/无法使用（最新版本）Firefox。但是在Firefox 26中可以使用。我不知道为什么它不起作用。它仅使用边框宽度＆amp;背景颜色。

.loader.pulse {
  width: 40px;
  height: 40px;
  border: 20px solid red;
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  border-radius: 50%;
  -moz-border-radius: 50%;
  -webkit-border-radius: 50%;
  animation: Loader 1.3s linear 0 infinite;
  -moz-animation: Loader 1.3s linear 0 infinite;
  -webkit-animation: Loader 1.3s linear 0 infinite;
  -o-animation: Loader 1.3s linear 0 infinite;
}

@-webkit-keyframes Loader {
  0% {
    background: #ddd;
    border: 20px solid red;
  }
  49.9% {
    background: #ddd;
    border: 0px solid red;
  }
  50% {
    background: red;
    border: 20px solid #ddd;
  }
  100%{
    background: red;
    border: 0px solid #ddd;
  }
}

@-moz-keyframes Loader {
  0% {
    background: #ddd;
    border: 20px solid red;
  }
  49.9% {
    background: #ddd;
    border: 0px solid red;
  }
  50% {
    background: red;
    border: 20px solid #ddd;
  }
  100%{
    background: red;
    border: 0px solid #ddd;
  }
}

@keyframes Loader {
  0% {
    background: #ddd;
    border: 20px solid red;
  }
  49.9% {
    background: #ddd;
    border: 0px solid red;
  }
  50% {
    background: red;
    border: 20px solid #ddd;
  }
  100%{
    background: red;
    border: 0px solid #ddd;
  }
}

Firefox 26似乎将0中的animation: Loader 1.3s linear 0 infinite解释为时间值，即使它不应该。如果您更改为0s，它应该有效。 http://jsfiddle.net/ts9AG/1/

-moz-animation: Loader 1.3s linear 0s infinite;
-webkit-animation: Loader 1.3s linear 0s infinite;
-o-animation: Loader 1.3s linear 0s infinite;
animation: Loader 1.3s linear 0s infinite;

这个动画（css3）不适用于Firefox
