如何在Bootstrap中创建可滚动的列（） _WordPress主题

我在Wordpress主题中创建了一个新的模板文件template-home2.php。
在那里, 我有一行包含3列的行, 我想使这些列中的每一个都滚动而不是整个页面。我该如何实现？
我有一个可滚动的类, 该类可应用于页面的外部以使其可滚动。

< section class="< ?php if( get_theme_mod( 'hide-player' ) == 0 ){ echo "w-f-md"; } ?> " id="ajax-container"> < section class="hbox stretch bg-black dker"> < section> < section class="vbox"> < section class="scrollable"> < div class="row"> < div class="col-md-5 no-padder no-gutter"> some data < /div> < div class="col-md-4 no-padder no-gutter"> some data < /div> < div class="col-md-3 no-padder no-gutter"> some data < /div> < /div> < /section> < /section> < /section> < /section> < /section>

【如何在Bootstrap中创建可滚动的列（）】当我从主要部分中删除” 可滚动” 类并将其包括在div列中时, 该列消失, 其他2列在下面的元素上溢出。
这是相关的CSS

.scrollable { overflow-x: hidden; overflow-y: auto; } .no-touch .scrollable.hover { overflow-y: hidden; } .no-touch .scrollable.hover:hover { overflow: visible; overflow-y: auto; } .slimScrollBar { border-radius: 5px; border: 2px solid transparent; border-radius: 10px; background-clip: padding-box !important; }

感谢你的帮助。
更新的代码

.homecol1, .homecol2, .homecol3 { position: absolute; overflow-y: scroll; }< section class="< ?php if( get_theme_mod( 'hide-player' ) == 0 ){ echo "w-f-md"; } ?> " id="ajax-container"> < section class="hbox stretch bg-black dker"> < section> < section class="vbox"> < section class="scrollable"> < div class="row"> < div class="col-md-5 no-padder no-gutter homecol1"> some data < /div> < div class="col-md-4 no-padder no-gutter homecol2"> some data < /div> < div class="col-md-3 no-padder no-gutter homecol3"> some data < /div> < /div> < /section> < /section> < /section> < /section> < /section>

#1为此, 你首先需要为每个列提供一个类。然后, 你需要为其提供以下属性：

.your-class { position: absolute; overflow-y: scroll; }

你可能还想让自己的身体溢出：隐藏；
请告诉我这是否可行, 否则, 我会进一步帮助！
