I am trying to set up a little animation for my livestream that slides 3 images onto the screen from the left side, and once all 3 are on screen have them stay there for about 30 seconds then slide back off screen. I would like this 30 second animation to be automatically replayed every 15 minutes too.
I created an image to better help describe what I am trying to achieve here for my livestream.
This being said, I have a somewhat working version of this right now but it only sides in 1 image currently, here is the code:
<html>
<head>
<style>
.wrapper {
position: relative;
overflow: hidden;
width: 500px;
height: 500px;
}
#slide {
position: absolute;
left: -300px;
width: 300px;
height: 75px;
-webkit-animation: slide 30s 0s 1;
}
@keyframes slide {
0% { left: -330px }
3% { left: 0px }
97% { left: 0px }
100% { left: -330px }
}
</style>
</head>
<body>
<div class="wrapper">
<img id="slide" src="http://i.imgur.com/38Tfglv.png" />
</div>
</body>
</html>
Any input would be great. I have extremely limited knowledge on anything code related, this is all just from me scouring the internet and trying to figure this out. Thanks for any help!

This will work for you. Please check and let me know if you need to understand how it works.
