字幕内容未显示

Question

我设计了一个带有css关键帧的字幕包装器。但字幕内容没有显示。

我是根据https://codepen.io/nickcil/pen/BygPMY

设计的

但是不知道为什么字幕内容没有显示出来。 动画和所有这些东西都可以正常工作。 先生，请帮助我确定问题所在。

.landing-ratecard-wrapper {
  position: relative;
  padding: 15px 20px;
  background-color: rgba(0, 0, 0, 0.45);

  margin-top: 40px;
}

您缺少身高

.landing-ratecard-wrapper .marquee {
      flex-grow: 1;
      overflow: hidden;
      box-sizing: border-box;
      position: relative;
      height: 150px;
    }

还在类landing-ratecard-wrapper .marquee .marquee--inner中将top设置为0

.landing-ratecard-wrapper {
  position: relative;
  padding: 15px 20px;
  background-color: rgba(0, 0, 0, 0.45);
  border-radius: 4px;
  margin-top: 40px;
}
.landing-ratecard-wrapper .ratecard-title {
  color: #fff;
  font-weight: 500;
  font-size: 18px;
  margin: 0;
}
.landing-ratecard-wrapper .marquee {
  flex-grow: 1;
  overflow: hidden;
  box-sizing: border-box;
  position: relative;
  height: 150px;
}
.landing-ratecard-wrapper .marquee .marquee--inner {
  display: block;
  width: 200%;
  position: absolute;
  top: 0;
  animation: marquee 20s linear infinite;
}
.landing-ratecard-wrapper .marquee .marquee--inner span {
  width: 50%;
  float: left;
}
.landing-ratecard-wrapper .marquee .marquee--inner span .rate {
  width: 200px;
  display: inline-block;
  margin: 0 10px;
  float: left;
  transition: all 0.2s ease-out;
  color: #fff;
}
.landing-ratecard-wrapper .marquee .marquee--inner:hover {
  animation-play-state: paused;
}
@keyframes marquee {
  0% {
    left: 0;
  }
  100% {
    left: -100%;
  }
}
