Hello,
Unfortunately, your Image Type is not currently supported. The Kind of Effect you are planning to Apply for your Image can only be applied by using Multiple Images. Please check out the Example on Our Christmas Demos: http://themes.semicolonweb.com/html/canvas/demo-xmas.php .
Here is the CSS Code that made this Animation possible:
.snowfall {
background-image: url('images/snow/s1.png'),
url('images/snow/s2.png'),
url('images/snow/s3.png');
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
-webkit-animation: snow 10s linear infinite;
-moz-animation: snow 10s linear infinite;
-ms-animation: snow 10s linear infinite;
animation: snow 10s linear infinite;
}
@keyframes snow {
0% {background-position: 0px 0px, 0px 0px, 0px 0px;}
50% {background-position: 500px 500px, 100px 200px, -100px 150px;}
100% {background-position: 500px 1000px, 200px 400px, -100px 300px;}
}
@-moz-keyframes snow {
0% {background-position: 0px 0px, 0px 0px, 0px 0px;}
50% {background-position: 500px 500px, 100px 200px, -100px 150px;}
100% {background-position: 400px 1000px, 200px 400px, 100px 300px;}
}
@-webkit-keyframes snow {
0% {background-position: 0px 0px, 0px 0px, 0px 0px;}
50% {background-position: 500px 500px, 100px 200px, -100px 150px;}
100% {background-position: 500px 1000px, 200px 400px, -100px 300px;}
}
@-ms-keyframes snow {
0% {background-position: 0px 0px, 0px 0px, 0px 0px;}
50% {background-position: 500px 500px, 100px 200px, -100px 150px;}
100% {background-position: 500px 1000px, 200px 400px, -100px 300px;}
}
