I have been experimenting with using a sprite and CSS3 animation to create a rollover effect. While it seems to be working in CODA 2, I'm encountering issues when testing in Mozilla, Chrome, Safari, and Opera as the animation fails to trigger.
/*linkedin contact button*/
button{text-indent:-99999px; border: none; }
a.linkedin,a.linkedin:hover{display: block; cursor: pointer; background: url(../img/linked.png) no-repeat; width: 128px; height: 128px}
a.linkedin{background-position: -0 -0}
a.linkedin:hover{animation:first 1000s; -moz-animation:first 1000s; -webkit-animation:first 1000s; -o-animation:first 1000s;}
@keyframes first{from {background-position: -140px -0;} to {background-position: -0px -0;}}
@-moz-keyframes first{from {background-position: -140px -0;} to {background-position: -0 -0;}}
@-webkit-keyframes first{from {background-position: -140px -0;} to {background-position: -0 -0;}}
@-o-keyframes first{from {background-position: -140px -0;} to {background-position: -0 -0;}}
*a.linkedin:hover{background-position: -140px -0/9}/*for ie*/
