CSS Flip Animation on time? - html

Question

Using David Walsh css flip effect for an image that suppose to change to another. But wondering If it can be triggered in say 3 seconds instead of mouseover? Sorry! Kind on a n00b to this. :(
Any response will be very appreciated :)
CSS Flip homepage: http://davidwalsh.name/css-flip
The Code:
<div class="flip-container" ontouchstart="this.classList.toggle('hover');">
<div class="flipper">
<div class="front">
<!-- front content -->
</div>
<div class="back">
<!-- back content -->
</div>
</div>
</div>
The CSS:
/* entire container, keeps perspective */
.flip-container {
perspective: 1000;
}
/* flip the pane when hovered */
.flip-container:hover .flipper, .flip-container.hover .flipper {
transform: rotateY(180deg);
}
.flip-container, .front, .back {
width: 320px;
height: 480px;
}
/* flip speed goes here */
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
/* hide back of pane during swap */
.front, .back {
backface-visibility: hidden;
position: absolute;
top: 0;
left: 0;
}
/* front pane, placed above back */
.front {
z-index: 2;
/* for firefox 31 */
transform: rotateY(0deg);
}
/* back, initially hidden pane */
.back {
transform: rotateY(180deg);
}

You'll want to use CSS animations instead of transitions on hover. Using animation-fill-mode: forwards the animation will only play once. You'll have to alter it if you want it to flip back over. animation-delay is used to make it wait 3 seconds.
Here's a resource for using CSS animations: MDN docs
#-webkit-keyframes flip {
from { -webkit-transform: rotateY(0deg); transform: rotateY(0deg); }
to { -webkit-transform: rotateY(180deg); transform: rotateY(180deg); }
}
#keyframes flip {
from { -webkit-transform: rotateY(0deg); transform: rotateY(0deg); }
to { -webkit-transform: rotateY(180deg); transform: rotateY(180deg); }
}
.flipper {
-webkit-animation-name: flip;
animation-name: flip;
-webkit-animation-duration: 0.6s;
animation-duration: 0.6s;
-webkit-animation-fill-mode: forwards;
animation-fill-mode: forwards;
-webkit-animation-delay: 3s;
animation-delay: 3s;
}
#-webkit-keyframes flip {
from { -webkit-transform: rotateY(0deg); transform: rotateY(0deg); }
to { -webkit-transform: rotateY(180deg); transform: rotateY(180deg); }
}
#keyframes flip {
from { -webkit-transform: rotateY(0deg); transform: rotateY(0deg); }
to { -webkit-transform: rotateY(180deg); transform: rotateY(180deg); }
}
/* entire container, keeps perspective */
.flip-container {
perspective: 1000;
}
.flip-container, .front, .back {
width: 320px;
height: 480px;
}
/* flip speed goes here */
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
-webkit-animation-name: flip;
animation-name: flip;
-webkit-animation-duration: 0.6s;
animation-duration: 0.6s;
-webkit-animation-fill-mode: forwards;
animation-fill-mode: forwards;
-webkit-animation-delay: 3s;
animation-delay: 3s;
}
/* hide back of pane during swap */
.front, .back {
backface-visibility: hidden;
position: absolute;
top: 0;
left: 0;
}
/* front pane, placed above back */
.front {
background: blue;
z-index: 2;
/* for firefox 31 */
transform: rotateY(0deg);
}
/* back, initially hidden pane */
.back {
transform: rotateY(180deg);
background: green;
}
