javascript - 光滑的 slider 跳跃

Question

我在页面上使用光滑的 slider 。一切都很好，除了一件事:当我拖动幻灯片时，有时图像或文本会弹起，这看起来非常糟糕。我该怎么做才能避免这个问题？

这是我的 code

  <section class="portfolio" id="portfolio">

        <div class="container" style="height:100px">
            <div class="row">
                <div class="col-lg-12"></div>
                </div>
            </div>
                <div id="portfolio_slider">
                    <div id="item">
                        <div class="container">
                            <div class="row">
                                <div class="col-lg-3 col-md-3 text-right">
                                    <div id="project_name">
                                        PROJECT<br />
                                        NAME
                                    </div>
                                    <div id="project-info">

在代码笔中，在 CSS 中，有一个类，#portfolio_slider #item 和 margin: top 20px 将其删除。
