我嘗試制作一個1秒鐘后就固定的DIV動畫。但是我做不到。我希望在一秒鐘后，名為“主頁-英雄-模塊”的div從右向左滑動。正如你在小提琴中看到的，它在一秒鐘后變成固定的。那么如何制作動畫呢？

我試過css，但是沒有成功。

-webkit-transition: left 1s;
  -moz-transition: left 1s;
  -o-transition: left 1s;
  transition: left 1s;

和

-webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;

JSFIDDLE

HTML代碼:

<div class="container-fluid">
    <div class="homepage-hero-module">
        Container with data
    </div>
</div>

CSS代碼:

body, html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  background: #DDD;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0px;
  left: 0px;
}
.fixed {
    position: fixed;
    top: 0px;
    left: 0px;
    width: 20px;
    height: 100%;
    background: red;
}
img {
  height: 100%;
  width: auto;
}

JS代碼:

$(document).ready(function() {
    setTimeout( function(){
              $('.homepage-hero-module').addClass('fixed');
    },1000);
});

您需要在位置仍然是絕對的情況下制作寬度動畫，然后將位置設置為固定

<div class="container-fluid">
    <div class="homepage-hero-module">
        Container with data
    </div>
</div>

body, html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  background: #DDD;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0px;
  left: 0px;
  transition:all .2s ease;
}
.fixed {
    top: 0px;
    left: 0px;
    width: 20px;
    height: 100%;
    background: red;
}
img {
  height: 100%;
  width: auto;
}

$(document).ready(function() {
  setTimeout( function(){
    $('.homepage-hero-module').addClass('fixed');
  },1000);

  $('.homepage-hero-module').css('position','fixed');
});

我猜已經開始工作了，檢查下面的片段，讓我知道你的反饋。謝謝！

$(document).ready(function() {
  setTimeout(function() {
    $('.homepage-hero-module').addClass('fixed');
  }, 1000);
});

body,
html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  background: #DDD;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0px;
  left: 0px;
}
.fixed {
  position: fixed;
  top: 0px;
  left: 0px;
  width: 20px;
  height: 100%;
  background: red;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
img {
  height: 100%;
  width: auto;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container-fluid">
  <div class="homepage-hero-module">
    Container with data
  </div>
</div>

只要用CSS就可以了。檢查CSS3動畫。

現場演示:

body,
html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  min-height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  width: 100%;
  height: 100vh;
  position: absolute;
  top: 0px;
  left: 0px;
  background-color: #f5f5f5;
  animation: slideleft 1s 0.3s ease-out forwards;
}
img {
  height: 100%;
  width: auto;
}
@keyframes slideleft {
  to {
    background: coral;
    width: 70px;
    position: fixed;
  }
}

<div class="container-fluid">
  <div class="homepage-hero-module">
    Container with data
  </div>
</div>
