Effect to reveal the text from left to right in pure css-CodePudding

I would like to create a effect to reveal to text like my codesandbox. Instead of using animation mask-image, do I have any other option?

.animation-text-wipe {
  -webkit-mask-image: linear-gradient(
    to left,
    rgba(255, 255, 255, 0) 75%,
    #000 75%
  );
  -webkit-mask-size: 500%;
}

.animation-text-wipe.animate-in {
  animation-name: text-wipe;
  animation-duration: 5s;
  animation-timing-function: linear;
  animation-delay: 0.1s;
  animation-iteration-count: infinite;
  animation-fill-mode: forwards;
}

@keyframes text-wipe {
  0% {
    opacity: 1;
    -webkit-mask-position: 100%;
  }

  100% {
    opacity: 1;
    -webkit-mask-position: 0%;
  }
}
.text {
  width: 60%;
  color: #000;
  background-color: #ffff;
}

.app {
  background-color: red;
}

              real-world studies published Wednesday confirm that the immune
              protection offered by two doses of Pfizer's Covid-19 vaccine drops
              off after two months or so, although protection against severe
              disease, hospitalization and death remains strong. The studies,
              from Israel and from Qatar and published in the New England
              Journal of Medicine, support arguments that even fully vaccinated
              people need to maintain precautions against infection. One study
              from Israel covered 4,800 health care workers and showed antibody
              levels wane rapidly after two doses of vaccine "especially among
              men, among persons 65 years of age or older, and among persons
              with immunosuppression." Vaccines may have prevented a
              quarter-million Covid-19 cases and 39,000 deaths among seniors

              longitudinal cohort study involving health care workers at Sheba
              Medical Center, a large tertiary medical center in Israel,"
              Sheba's Dr. Gili Regev-Yochay and colleagues wrote. The
              researchers noted that levels of so-called neutralizing antibodies
              -- the immune system's first line of defense against infection --
              correlate with protection against infection, but for this study
              they studied only antibody levels.
