html – 用于可变消息长度的CSS Marquee

我正在寻找marquee标签替代品,并找到了如何通过CSS进行此操作.但是我使用的消息是可变长度的,所以可以选择将’45s’属性设置为100％,这样无论消息有多长或多短,消息都会显示所有消息和循环消息显示后再次显示？

.marquee {
  margin: 0 auto;
  white-space: Nowrap;
  overflow: hidden;
  position: absolute;
  color: #ffffff;
  background-color: #000000;
  font-family: Arial Rounded MT Bold;
}

.marquee span {
  display: inline-block;
  padding-left: 100%;  /* show the marquee just outside the paragraph */
  animation: marquee 45s linear infinite;
}


@keyframes marquee {
  from  { text-indent:  0%}
  to    { text-indent: -150% }
}

<p id="PassengerNews_Scrollbar" class="microsoft marquee" style="height: 95%;  width: 90%;left: 5%;top: 2%;font-size: 7%;">
  <span>|*NewsData*|</span>
</p>
