.click-block ionic serve css != build css

[tienne]

ionic serve main.css

.click-block {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 9999;
  display: block;
  opacity: 0;
  -webkit-transform: translate3d(0, -100%, 0);
  transform: translate3d(0, -100%, 0);
  -webkit-transform: translate3d(0, calc(-100% + 1px), 0);
  transform: translate3d(0, calc(-100% + 1px), 0); }

but ionic build main.css

.click-block{
  position:absolute;
  top:0;
  right:0;
  bottom:0;
  left:0;
  z-index:9999;
  display:block;
  opacity:0;
  -webkit-transform:translate3d(0,calc(-100% + 1px),0);
  transform:translate3d(0,calc(-100% + 1px),0)}

Why is the difference?
