jQuery - 淡入淡出无法正常工作

Question

我有一个动画,其中标题淡出然后一些内容淡入,我对动画的速度有一点问题.

无论我做什么我都无法改变fadeIn方法的速度效果？动画与此完美结合.似乎无法弄明白 - 任何想法？

$(document).ready(function() {
  $('.aboutQuery').click(function() {
    $('.mySec').fadeOut('slow', function() {
      $('.aboutText').fadeIn(5000);
    })
  })
})

.mySec {
  display: block;
  position: relative;
  height: calc(95vh);
  width: calc(96vw - 1vh);
  transform: translate(calc((4vw + 1vh) / 2), 2.5vh);
  overflow: hidden;
}

.aboutText {
  padding-left: 5vw;
  padding-right: 5vw;
  font-size: 2vw;
  white-space: pre-line;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<div class="header">
  <ul id="headList">
    <li>
      <a class="aboutQuery" id="link" href="#">ABOUT</a>
    </li>
    <li>
      <a id="link" href="#">CLASSES</a>
    </li>
    <li>
      <a id="link" href="#">CONTACT</a>

  </ul>
  <div class="mySec">
    <div class="info">

      <p class="title2">Working From The Inside Out.</p>
      <img id="pilLogo" src="pilatesLog.png">

  </div>
  <div class="aboutSec">
    <div class="aboutInfo">
      <p class="aboutText">

Answer 1

您没有先隐藏about文本.您需要添加display:none到CSS规则:

.aboutText {
  padding-left: 5vw;
  padding-right: 5vw;
  font-size: 2vw;
  white-space: pre-line;
  display:none;
}

$('.aboutQuery').click(function() {
    $('.mySec').fadeOut('slow', function() {
      $('.aboutText').fadeIn(5000);
    })
  })

.mySec {
  display: block;
  position: relative;
  height: calc(95vh);
  width: calc(96vw - 1vh);
  transform: translate(calc((4vw + 1vh) / 2), 2.5vh);
  overflow: hidden;
}

.aboutText {
  padding-left: 5vw;
  padding-right: 5vw;
  font-size: 2vw;
  white-space: pre-line;
  display:none;
}
