我的CSS动画无法在iOS中使用 [英] My CSS animations are not working in iOS

问题描述

请查看 http://facelesstolegendary.com

我在这里查看了几篇文章，发现我需要在转换中添加 -webkit-前缀，等等。

I looked at several posts here and saw that I need to add the -webkit- prefix to my transforms, etc.

我这样做了，但是在iOS上仍然不起作用。它可以在我的桌面浏览器上运行。

I did that, but it still does not work on iOS. It does work on my desktop browsers.

以下是相关代码：

.cb-slideshow,
.cb-slideshow:after { 
    position: fixed;
    width: 100%;
    height: 100%;
    top: 0px;
    left: 0px;
    z-index: 0; 
}
.cb-slideshow:after { 
    content: '';
    background: transparent url(pattern.png) repeat top left; 
}

.cb-slideshow li span { 
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0px;
    left: 0px;
    color: transparent;
    background-size: cover;
    background-position: 50% 50%;
    background-repeat: none;
    opacity: 0;
    -webkit-opacity: 0;
    z-index: 0;
    animation: imageAnimation 36s linear infinite 0s; 
    -webkit-animation: imageAnimation 36s linear infinite 0s; 
}

.cb-slideshow li div { 
    z-index: 1000;
    position: absolute;
    bottom: 30px;
    left: 0px;
    width: 100%;
    text-align: center;
    opacity: 0;
    -webkit-opacity: 0;
    color: #fff;
    animation: titleAnimation 36s linear infinite 0s; 
    -webkit-animation: titleAnimation 36s linear infinite 0s; 
}
.cb-slideshow li div h3 { 
    font-family: 'BebasNeueRegular', 'Arial Narrow', Arial, sans-serif;

推荐答案

您需要为 @keyframes 加上 -webkit-前缀，并包含 -webkit-在其中添加了固定的动画和过渡效果，而不是将它们包含在原始的 @keyframes ：

You need to prefix your @keyframes with -webkit-, and include the -webkit-prefixed animations and transitions there, instead of including them in your original @keyframes:

@keyframes imageAnimation { 
    0% {
        opacity: 0;
        -webkit-opacity: 0;
        animation-timing-function: ease-in;
        -webkit-animation-timing-function: ease-in;
    }

成为：

@-webkit-keyframes imageAnimation {
    0% {
        -webkit-opacity: 0;
        -webkit-animation-timing-function: ease-in;
    }

@keyframes imageAnimation {
    0% {
        opacity: 0;
        animation-timing-function: ease-in;
    }

，依此类推。
