标签: css bootstrap-4

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: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;
}
