javascript - 具有滚动效果的固定背景？

Question

我被我的代码困住了，我正在尽最大努力创建一个背景固定的 CSS，使用 jQuery 滚动，就像这样:http://goo.gl/knvjda

如您所见，它会针对每个 div 和部分上下滚动。

到目前为止，这是我的 HTML 中的内容:

<header class="header">
        <h1>Fixed Background Effect</h1>
    </header>

    <section class="background-fixed img-1">
        <div class="main-content">
            <h2>Title here</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Autem dolor beatae, laudantium eos fugiat, deserunt delectus quibusdam quae placeat, tempora ea? Nulla ducimus, magnam sunt repellendus modi, ad ipsam est.</p>
        </div>
    </section>

    <section class="background-fixed img-2">
        <div class="main-content light-background">
            <h2>Title here</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Autem dolor beatae, laudantium eos fugiat, deserunt delectus quibusdam quae placeat, tempora ea? Nulla ducimus, magnam sunt repellendus modi, ad ipsam est.</p>
        </div>
    </section>

    <section class="background-fixed img-3">
        <div class="main-content">
            <h2>Title here</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Autem dolor beatae, laudantium eos fugiat, deserunt delectus quibusdam quae placeat, tempora ea? Nulla ducimus, magnam sunt repellendus modi, ad ipsam est.</p>
        </div>
    </section>

    <section class="background-fixed img-4" data-type="slider-item">
        <div class="main-content">
            <h2>Title here</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Autem dolor beatae, laudantium eos fugiat, deserunt delectus quibusdam quae placeat, tempora ea? Nulla ducimus, magnam sunt repellendus modi, ad ipsam est.</p>
        </div>
    </section>


<footer>

这是我的 CSS:

.background-fixed .light-background h2, .background-fixed .light-background p {

.background-fixed .main-content::after {
  /* phone image on small devices */
  content: '';
  display: block;
  width: 100%;
  padding: 60% 0;
  margin: 2em auto 0;
}
.background-fixed.img-1 {

}


.background-fixed.img-2 {

}

.background-fixed.img-3 {

  }
  .background-fixed h2 {

    font-weight: 300;
  }
  .background-fixed p {
    font-size: 1.8rem;
    line-height: 1.8;
  }

  .background-fixed.img-1 {
    background-image: url("http://halloweenmaternitycostumes.com/wp-content/uploads/2015/06/img-1.jpg");
  }
  .background-fixed.img-2 {
    background-image: url("http://halloweenmaternitycostumes.com/wp-content/uploads/2015/06/img-2.jpg");
  }
  .background-fixed.img-3 {
    background-image: url("http://halloweenmaternitycostumes.com/wp-content/uploads/2015/06/img-3.jpg");
  }
  .background-fixed.img-4 {
    background-image: url("http://halloweenmaternitycostumes.com/wp-content/uploads/2015/06/img-4.jpg");
  }
}


footer {
  background: #dadada;
  padding: 15px 0;

}

footer p{
  color: #000;
  text-align:center;
}

这是我的 JSFIDDLE:https://jsfiddle.net/v7a58odd/1/

非常感谢任何能帮助我的人。
