我正在使用here中的以下代码段(如下所示) 使列表组中的项目水平对齐(在Bootstrap 4中)。
.list-group.list-group-horizontal{
display: flex;
flex-direction: row;
}
.list-group.list-group-horizontal .list-group-item {
margin-bottom: 0;
margin-right: 0;
border-right-width: 0;
}
.list-group.list-group-horizontal .list-group-item:first-child {
border-top-right-radius:0;
border-bottom-left-radius:4px;
}
.list-group.list-group-horizontal .list-group-item:last-child {
border-top-right-radius:4px;
border-bottom-left-radius:0;
border-right-width: 1px;
}
我如何居中对齐列表组?我尝试添加类text-center
和其他一些东西,但是没有成功。
<div id="app" class="container my-container">
<!-- Header -->
<h2 class="text-center" >Sample Header</h2>
<!-- Buttons -->
<div class="list-group list-group-horizontal">
<a href="#" class="list-group-item active">Categories</a>
<a href="#" class="list-group-item">Search</a>
</div>
</div>

对于后代:
如果您的元素不是flex元素,则应用closeLabelPressed
。
原始答案:
将LabelTest.start
应用于d-flex justify-content-center

justify-content-center

使用Justify content来更改元素的水平位置:
.list-group.list-group-horizontal {
display: flex;
flex-direction: row;
}
.list-group.list-group-horizontal .list-group-item {
margin-bottom: 0;
margin-right: 0;
border-right-width: 0;
}
.list-group.list-group-horizontal .list-group-item:first-child {
border-top-right-radius:0;
border-bottom-left-radius:4px;
}
.list-group.list-group-horizontal .list-group-item:last-child {
border-top-right-radius:4px;
border-bottom-left-radius:0;
border-right-width: 1px;
}
