如何使这个js动画效果的多线&； 一个接一个地做动画？

就像

<h1 class="rks1">  First Line </h1>
<h1 class="rks1">  Then Second Line </h1>
<h1 class="rks1">  Then Third Line </h1>
<h1 class="rks1">  Then Fourth Line </h1>
<h1 class="rks1">  Then Fifth Line </h1>

(&P； 更多。。。 然后重启第一行或者我认为它可能像:

<h1 class="rks1">  First Line </h1>
<h1 class="rks2">  Then Second Line </h1>
<h1 class="rks3">  Then Third Line </h1>
<h1 class="rks4">  Then Fourth Line </h1>
<h1 class="rks5">  Then Fifth Line </h1>

(&P； 更多。。。 然后重新启动第一行

var textWrapper = document.querySelector('.rks1');

textWrapper.innerHTML = textWrapper.textContent.replace(/(\S*)/g, m => {
  return `<span class="word">` +
    m.replace(/(-|)?\S(-|@)?/g, "<span class='letter'>$&</span>") +
    `</span>`;
});

var targets = Array.from(document.querySelectorAll('.rks1 .letter'));

anime.timeline({
  loop: true,
})
  .add({
    targets: targets,
    scale: [3,1],
    scaleY: [1.5,1],
    opacity: [0,1],
    translateZ: 0,
    easing: "easeOutExpo",
    duration: 400,
    delay: (el, i) => 60*i
  }).add({
    targets: targets.reverse(),
    scale: [1,3],
    scaleY: [1,1.5],
    opacity: [1,0],
    translateZ: 0,
    easing: "easeOutExpo",
    duration: 100,
    delay: (el, i) => 30*i
  }).add({
    opacity: 0,
    duration: 2000,
    easing: "easeOutExpo",
    delay: 800
  });

.rks1 {
font-weight: 900;
font-size: 2.5em;
font-family: rr;
}

.rks1 .letter {
display: inline-block;
line-height: 1em;
}

.word {
white-space: nowrap;
}

.span {
}
