CSS Animation for Scrolling Text Doesn't Work on Safari - html

Question

I'm trying to have a scrolling marquee of sorts across the top of my webpage. I'm not using the tag as it is not supported by Safari. However, even with using CSS Animation, it doesn't seem to work for Safari either. Here's my code:
<h3>Upcoming Shows:...</h3>
This is what I have in my style sheet:
h3 {
position: absolute;
width: 100%;
height: 100%;
margin: 0;
line-height: 50px;
text-align: center;
/* Starting position */
-moz-transform:translateX(100%);
-webkit-transform:translateX(100%);
transform:translateX(100%);
/* Apply animation to this element */
-moz-animation: example1 15s linear infinite;
-webkit-animation: example1 15s linear infinite;
animation: example1 15s linear infinite;
}
/* Move it (define the animation) */
#-moz-keyframes example1 {
0% { -moz-transform: translateX(100%); }
100% { -moz-transform: translateX(-100%); }
}
#-webkit-keyframes example1 {
0% { -webkit-transform: translateX(100%); }
100% { -webkit-transform: translateX(-100%); }
}
#keyframes example1 {
0% {
-moz-transform: translateX(100%); /* Firefox bug fix */
-webkit-transform: translateX(100%); /* Firefox bug fix */
transform: translateX(100%);
}
100% {
-moz-transform: translateX(-100%); /* Firefox bug fix */
-webkit-transform: translateX(-100%); /* Firefox bug fix */
transform: translateX(-100%);
}
}
