我的 CSS 动画在 iOS 中不工作

Question

我看了这里的几个帖子，发现我需要为我的转换等添加 -webkit- 前缀。

我这样做了，但在 iOS 上仍然不起作用。它可以在我的桌面浏览器上运行。

相关代码如下：

.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;
    font-size: 240px;
    padding: 0;
    line-height: 200px; 
}

.cb-slideshow li:nth-child(1) span { 
    background-image: url(faceless.jpg) 
}
.cb-slideshow li:nth-child(2) span { 
    background-image: url(legendary.jpg);
    animation-delay: 6s; 
    -webkit-animation-delay: 6s; 
}
.cb-slideshow li:nth-child(3) span { 
    background-image: url(faceless.jpg);
    animation-delay: 12s; 
    -webkit-animation-delay: 12s; 
}
.cb-slideshow li:nth-child(4) span { 
    background-image: url(legendary.jpg);
    animation-delay: 18s; 
    -webkit-animation-delay: 18s; 
}
.cb-slideshow li:nth-child(5) span { 
    background-image: url(faceless.jpg);
    animation-delay: 24s; 
    -webkit-animation-delay: 24s; 
}
.cb-slideshow li:nth-child(6) span { 
    background-image: url(legendary.jpg);
    animation-delay: 30s; 
    -webkit-animation-delay: 30s; 
}

.cb-slideshow li:nth-child(2) div { 
    animation-delay: 6s; 
    -webkit-animation-delay: 6s; 
}
.cb-slideshow li:nth-child(3) div { 
    animation-delay: 12s; 
    -webkit-animation-delay: 12s; 
}
.cb-slideshow li:nth-child(4) div { 
    animation-delay: 18s; 
    -webkit-animation-delay: 18s; 
}
.cb-slideshow li:nth-child(5) div { 
    animation-delay: 24s; 
    -webkit-animation-delay: 24s; 
}
.cb-slideshow li:nth-child(6) div { 
    animation-delay: 30s; 
    -webkit-animation-delay: 30s; 
}

.no-cssanimations .cb-slideshow li span{
 opacity: 1;
 -webkit-opacity: 1;
}

@media screen and (max-width: 1140px) {

}
@media screen and (max-width: 600px) { 
    .cb-slideshow li div h3 { font-size: 80px }

Answer 1

您需要在 @keyframes 前加上 -webkit- 前缀，并在其中包含 -webkit- 前缀动画和过渡，而不是将它们包含在原始 @keyframes 中：

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

变成：

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

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

等等。

你是不是在别处写了-webkit-overflow-scrolling: touch;，删掉试试
