我需要在小屏幕尺寸上使用水平列表组,但是我能找到的唯一解决方案与此相反。列表组水平的工作方式-在小屏幕上垂直,在屏幕增长时水平。在这种情况下我该怎么办?我尝试创建2个不同的列表组,但是它们不能一起使用。

默认情况下,列表组的灵活方向为column
。对于小屏幕,您只需要将其设置为row
,对于大屏幕,只需将其重置为column
。为此,请使用 flex-*-column
和 flex-row
。

我用过flex-sm-*
。您可能需要使用flex-md-*
或flex-lg-*
。

此行为在Bootstrap中没有本机类。但是使用SASS创建一个很容易:
@include media-breakpoint-down(sm) {
.list-group-horizontal-sm-down {
flex-direction: row;
.list-group-item {
&:first-child {
@include border-bottom-left-radius($list-group-border-radius);
@include border-top-right-radius(0);
}
&:last-child {
@include border-top-right-radius($list-group-border-radius);
@include border-bottom-left-radius(0);
}
&.active {
margin-top: 0;
}
& + .list-group-item {
border-top-width: $list-group-border-width;
border-left-width: 0;
&.active {
margin-left: -$list-group-border-width;
border-left-width: $list-group-border-width;
}
}
}
}
}
这是用法的基本示例:
<ul class="list-group list-group-horizontal-sm-down">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
