Blink not working in Chrome

blink, .blink {
    -webkit-animation: blink 1s step-end infinite;
    -moz-animation: blink 1s step-end infinite;
    -o-animation: blink 1s step-end infinite;
    animation: blink 1s step-end infinite;
}
@-webkit-keyframes blink { 67% { opacity: 0 }}
@-moz-keyframes blink {  67% { opacity: 0 }}
@-o-keyframes blink {  67% { opacity: 0 }}
@keyframes blink {  67% { opacity: 0 }}

It is deprecated so you might try to do it with javascript. Here is an example I made out of jquery for you: http://jsfiddle.net/FPsdy/ It is very simple:

window.setInterval(function(){
  $('.blink').toggle();
}, 250);

Blink is deprecated, and you should not use it.

Add following code to your css file,

blink {
-webkit-animation-name: blink; 
-webkit-animation-iteration-count: infinite; 
-webkit-animation-timing-function: cubic-bezier(1.0,0,0,1.0);
-webkit-animation-duration: 1s;
}
