Question

我有一个直接位于输入框旁边的选择框，（请参阅下面的相关摘录）。

目前，播放两个单独的过渡动画，以便在悬停时显示两个框。

我想只使用一个过渡来在悬停时显示两个框。有更清洁的方法吗？不同的定位属性能帮助我吗？提前谢谢！

<div *ngFor="let triple of device_triples">
    <div class="uk-child-width-expand@s uk-text-center" uk-grid>    
        <div *ngFor="let device of triple">
            <h2 class="uk-h2">{{ device.name }}</h2>
            ...
       <div>
    </div>
</div>

只需将输入和选择框包装到容器中并在其上设置动画，请使用下面的flexbox查看简化演示。您可以根据需要调整样式。
