如何在Bootstrap中创建可滚动列？

Question

我template-home2.php在Wordpress主题中创建了一个新的模板文件.

在那里我有一个3列的行,我想使这些列中的每一列都可滚动而不是整个页面.我怎样才能做到这一点？

我有一个类scrollable,我应用于页面的外部部分,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>

当我从主要部分删除"可滚动"类并将其包含在列div中时,列会消失,其他2列会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;
}

谢谢您的帮助.

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>

Answer 1

要实现这一点,您首先需要为每列提供一个class.然后你需要给他们以下属性:

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

您可能还想给您body的房产overflow: hidden;

请告诉我这是否有效,如果没有,我会进一步帮助!
