光滑-带有上一张/下一张幻灯片的名称的箭头

我正在尝试使用上一张/下一张幻灯片的标题做箭头（使用数据att“ data-slide-name”）。我搜索了整个互联网，但没有找到需要的东西。我有一张幻灯片（名称1），上一张幻灯片（猫），下一张幻灯片（狗）。我想用箭头显示幻灯片名称。例如，我附加了codepen（带有scss）：

的HTML

<div class="slide">
    <div class="slide__title">
        <h2>Lorem ipsum</h2>
    </div>

    <div class="slide__items">
        <div class="slide__item" data-slide-name="Cat">
            <div class="slide__box">
                <div class="slide__inner">
                    <div class="slide__content">
                        <h3>Cat</h3>
                        <p>Lorem ipsum ..</p>
                    </div>
                </div>
            </div>
        </div>
        <div class="slide__item" data-slide-name="Name1">
            <div class="slide__box">
