如何使用css动画更改css动画中的字体颜色 [英] How do I Change font-color in CSS animation using CSS animation

问题描述

我正在尝试这样做，当我打开页面时，test将显示为红色，testing将显示为白色。我希望保留打开页面时使用的延迟(如果运行程序，您将看到该延迟)。

css

#hero h1 {
  display: block;
  width: fit-content;
  font-size: 3rem;
  position: relative;
  color: transparent;
  animation: text_reveal .5s ease forwards;
  animation-delay: 1s;
}

#hero h1 .slide {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 0;
  background-color: crimson;
  animation: text_reveal_box 1s ease;
  animation-delay: .5s;
}


/* KetFrames */

@keyframes text_reveal_box {
  50% {
    width: 100%;
    left: 0;
  }
  100% {
    width: 0;
    left: 100%;
  }
}

@keyframes text_reveal {
  100% {
    color: white;
  }
}

HTML

<section id="hero">
  <div class="hero container">
    <div>
      <h1><span class="red">test</span> testing<span class="slide"></span></h1>
    </div>
  </div>
</section>
