我目前正在尝试通过复制以下内容来使用 stellar.js 查询插件实现视差背景：http: //markdalgleish.com/projects/stellar.js/demos/backgrounds.html

当调用 stellar 函数时，似乎没有任何变化。

这是我的尝试，对我哪里出错有任何想法吗？

        verticalOffset: 40
    });
});

我重新添加了 stellar.js 文件，它工作正常。我认为您的问题是所有视差速度都设置为相同，因此很难区分。我在这个小提琴中改变了一些速度，你可以分辨出来 -

<div class="photo summer" data-stellar-background-ratio="2"><span>Summer</span></div>
<div class="photo autumn" data-stellar-background-ratio="0.5"><span>Autumn</span></div>
