如何让幻灯片中的第一个文本在 300 毫秒后显示？

所有人的过渡时间都是 4 秒，但我只想在 300 毫秒后显示第一个文本，之后其他所有内容都可以过渡 4 秒

我不想等 4 秒直到幻灯片放映开始

setInterval 函数用于整个幻灯片

setInterval(function(){
  $('.blurtext span.past').removeClass('past');
  $('.blurtext span.active').addClass('past').removeClass('active');
  $('.blurtext span.past + span').addClass('active');
  if ($('.blurtext span.active').length == 0){
    $('.blurtext span:nth-child(1)').addClass('active');
  }
}, 4000);

.blurtext {
  position: relative;
  width: 100vw;
  text-align: center;
  font-size: 10vw;
  height: 10vw;
  text-transform: uppercase;
  font-family: "Oswald", sans-serif;
  font-weight: 600;
  color: #471C1A;
}
.blurtext span {
  position: absolute;
  display: block;
  width: 100%;
  text-align: center;
  opacity: 0;
  transform: perspective(100px) translateZ(10px);
  filter: blur(10px);
  letter-spacing: 0.1em;
}
.blurtext span.active {
  opacity: 1;
  transform: perspective(100px) translateZ(0px);
  filter: blur(0px);
  letter-spacing: 0.15em;
  transition: opacity 2000ms linear, transform 2000ms linear, filter 2000ms linear, letter-spacing 2000ms linear;
}
.blurtext span.past {
  opacity: 0;
  transform: perspective(100px) translateZ(-10px);
  filter: blur(10px);
  letter-spacing: 0.2em;
  transition: opacity 2000ms linear, transform 2000ms linear, filter 2000ms linear, letter-spacing 2000ms linear;
}

.center {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate3d(-50%, -50%, 0);
}

我认为最初只在一个单独的超时时间调用函数是可行的：

setTimeout(triggerNextSlide, 1000);

function triggerNextSlide() {
  $('.blurtext span.past').removeClass('past');
  $('.blurtext span.active').addClass('past').removeClass('active');
  $('.blurtext span.past + span').addClass('active');
  if ($('.blurtext span.active').length == 0){
    $('.blurtext span:nth-child(1)').addClass('active');
  }
}

setInterval(triggerNextSlide, 4000);

.blurtext {
  position: relative;
  width: 100vw;
  text-align: center;
  font-size: 10vw;
  height: 10vw;
  text-transform: uppercase;
  font-family: "Oswald", sans-serif;
  font-weight: 600;
  color: #471C1A;
}
.blurtext span {
  position: absolute;
  display: block;
  width: 100%;
  text-align: center;
  opacity: 0;
  transform: perspective(100px) translateZ(10px);
  filter: blur(10px);
  letter-spacing: 0.1em;
}
.blurtext span.active {
  opacity: 1;
  transform: perspective(100px) translateZ(0px);
  filter: blur(0px);
  letter-spacing: 0.15em;
  transition: opacity 2000ms linear, transform 2000ms linear, filter 2000ms linear, letter-spacing 2000ms linear;
}
.blurtext span.past {
  opacity: 0;
  transform: perspective(100px) translateZ(-10px);
  filter: blur(10px);
  letter-spacing: 0.2em;
  transition: opacity 2000ms linear, transform 2000ms linear, filter 2000ms linear, letter-spacing 2000ms linear;
}

.center {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate3d(-50%, -50%, 0);
}
