My CSS animations are not working in iOS - html

Question

Please have a look at http://facelesstolegendary.com
I looked at several posts here and saw that I need to add the -webkit- prefix to my transforms, etc.
I did that, but it still does not work on iOS. It does work on my desktop browsers.
Here's the relevant code:
.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 {

Answer 1

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;
}
becomes:
#-webkit-keyframes imageAnimation {
0% {
-webkit-opacity: 0;
-webkit-animation-timing-function: ease-in;
}
#keyframes imageAnimation {
0% {
opacity: 0;
animation-timing-function: ease-in;
}
and so on.

Answer 2

Did you use -webkit-overflow-scrolling: touch; elsewhere? Try to delete it.
