引导程序：无法将整个行的内容居中

时间：2019-07-01 10:00:31

标签： html css bootstrap-4

我正在学习HTML5，CSS3和Bootstrap4，并创建了一个虚拟项目。

我正在尝试创建一行并排放置我的图标和文本（公司名称）并使用display:inline来实现的行。这之后是标记行。

但是，我无法获得中间整个行的内容。我尝试过text-center或text-xs-center，但无济于事。我什至创建了一个自定义CSS类

.text-center-custom{
    text-align: center !important;
}

但是那也不起作用。

在justify-content-center上使用row 作为参考，您可以浏览Bootstrap 4 flex utilities 希望对您有帮助

答案 1 :(得分：1)

您可以使用引导程序4 flex utilities通过使用d-flex justify-content-center行来实现。确保引导程序4没有类col-xs-12，它已被col-12

取代 

#topSection{
    background: url(images/background.jpg);
    background-position: center;
    background-size: 100%;
    color: bisque;
}

.inline{
    display: inline;
    font-family: 'B612', sans-serif;
}

.text-center-custom{
    text-align: center !important;
}
