Remove white space in CSS marquee

Question

I am trying to add a marquee effect with CSS3 animation in Wordpress as it doesn't support the <marquee> tag. I would like to get rid of the white space in between each loop. I tried using nowrap but it doesn't work.

@keyframes marquee {
  0% {
    text-indent: 430px
  }
  100% {
    text-indent: -485px
  }
}

@-webkit-keyframes marquee {
  0% {
    text-indent: 430px
  }
  100% {
    text-indent: -485px
  }
}

.marquee {
  font-size: 50px;
  overflow: hidden;
  white-space: nowrap;
  animation: marquee 12s linear infinite;
  -webkit-animation: marquee 12s linear infinite;
}

.marquee:hover {
  -webkit-animation-play-state: paused;
  animation-play-state: paused;
}

<p class="marquee">
  <a href="#">
    SOON SOON SOON SOON SOON SOON SOON </a></p>

It is not a good idea to using text-indent for transform. Use this instead of your animation:

@keyframes marquee {
0% {
transform: translateX(100vw);
 }
100% {
    transform: translateX(-100vw);
   }
}

@-webkit-keyframes marquee {
  0% {
    transform: translateX(100vw);
  }
100% {
    transform: translateX(-100vw);
  }
}

@keyframes marquee {
0% {
transform: translateX(100vw);
 }
100% {
    transform: translateX(-100vw);
   }
}

@-webkit-keyframes marquee {
  0% {
    transform: translateX(100vw);
  }
100% {
    transform: translateX(-100vw);
  }
}
.marquee {
  font-size: 50px;
  overflow: hidden;
  white-space: nowrap;
  animation: marquee 12s linear infinite;
  -webkit-animation: marquee 12s linear infinite;
}

.marquee:hover {
  -webkit-animation-play-state: paused;
  animation-play-state: paused;
}

<p class="marquee">
  <a href="#">
    SOON SOON SOON SOON SOON SOON SOON </a></p>
