Can I Apply CSS Rules to a Specific Div Only in Google Chrome?

position: relative;
top: -2px;

/* Chrome, Safari, AND NOW ALSO the Edge Browser and Firefox */
@media screen and (-webkit-min-device-pixel-ratio:0) {
  div{top:10;} 
}

/* Chrome 29+ */
@media screen and (-webkit-min-device-pixel-ratio:0)
  and (min-resolution:.001dpcm) {
    div{top:0;} 
}

/* Chrome 22-28 */
@media screen and(-webkit-min-device-pixel-ratio:0) {
  .selector {-chrome-:only(; 
     property:value;
  );} 
}

if (navigator.appVersion.indexOf("Chrome/") != -1) {
  // modify button 
}
