这是CSS：

        opacity: 1;
    }
    0%,
    25%,
    100% {
        opacity: 0;
    }

}

代码在Firefox（Ubuntu 14.04 LTS 64位版本42.0）中运行良好，但在Chrome（版本47.0.2526.73（64位））中看起来很奇怪。动画只进行一次循环（10s），然后消失。当我将鼠标悬停在它上面时，它会再次显示，然后在2秒后再次消失。

如何修复我的代码？

Answer 1

此问题与mix-blend-mode属性有关。看起来Chrome并不完全喜欢它，它在处理它时失败（可能是错误？）（即使根据caniuse.com Chrome支持它）。

如果您将其删除，动画在Chrome和Firefox中均可正常运行。您可以在此演示中看到它（and on your JSFiddle）：

Answer 2

它缺少其他语法，如：

animation-delay: 0s;
-webkit-animation-delay: 0s;
-moz-animation-delay: 0s;
-o-animation-delay: 0s;

和

animation: slideshow 10s infinite running;
-webkit-animation: slideshow 10s infinite running;
-moz-animation: slideshow 10s infinite running;
-o-animation: slideshow 10s infinite running;
