CSS3 关键帧动画在 Firefox 和 IE 中不起作用

Question

我的 css 代码适用于 chrome 和 safari，但不适用于 Firefox、IE 和 Opera。 当我创建 @keyframes rotate {} 时，对于其他浏览器，这不起作用 是这4行： animation-duration: 4s;
animation-timing-function: linear; animation-name:"rotate"; animation-iteration-count: infinite; 或关键帧方法？ 我该如何解决这个问题？

CSS：

@-webkit-keyframes rotate {
0% {
    -webkit-transform:translate(73px, 73px) rotate(0deg) translate(-73px, -73px) rotate(0deg);
    background-color:#2187e7;
    background-image: -moz-linear-gradient(90deg, #2187e7 25%, #a0eaff); 
    background-image: -webkit-linear-gradient(90deg, #2187e7 25%, #a0eaff); 
}  

  13% {
    -webkit-transform:translate(73px, 73px) rotate(45deg) translate(-73px, -73px) rotate(-45deg);

Answer 1

从动画名称中删除双引号（rotate 而不是"rotate"）。

然后它会工作：

Running demo

-webkit-animation-duration: 4s;
-webkit-animation-timing-function: linear;
-webkit-animation-name:rotate;
-webkit-animation-iteration-count: infinite;

-moz-animation-duration: 4s;
-moz-animation-timing-function: linear;
-moz-animation-name:rotate;
-moz-animation-iteration-count: infinite;

-ms-animation-duration: 4s;
-ms-animation-timing-function: linear;
-ms-animation-name:rotate;
-ms-animation-iteration-count: infinite;

-o-animation-duration: 4s;
-o-animation-timing-function: linear;
-o-animation-name:rotate;
-o-animation-iteration-count: infinite;

animation-duration: 4s;
animation-timing-function: linear;
animation-name:rotate;
animation-iteration-count: infinite;

请记住，无前缀属性必须始终位于供应商特定之后的最后一个。

P.S：如果您不知道，有些网站会在编译时（如 Prefixr）甚至在运行时（如 prefix-free）为您的代码添加前缀。

顺便说一句+1，你的动画很漂亮:)
