图片库的css渐变

Question

我已经设置了一个图像库。它像幻灯片一样过渡到下一张照片。我正试图弄清楚如何在幻灯片过渡到下一张图像时使图像褪色。我试着添加过渡和不透明度，但似乎做不好。谢谢你的帮助！

要产生淡入效果，可以使用以下方法，并且可以根据代码进行更改。

fade-in {
animation: fadeIn ease 20s;
-webkit-animation: fadeIn ease 20s;
-moz-animation: fadeIn ease 20s;
-o-animation: fadeIn ease 20s;
-ms-animation: fadeIn ease 20s;
}
@keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}

@-moz-keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}

@-webkit-keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}

@-o-keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}

@-ms-keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}
