html - 如何在父 div 中居中放置多个 div？

Question

我在一个父 div 中包含 3 个 div (class="row services")。

我怎样才能使三个 col s12 l3 div 集中在这个父 div 中？

我试过使用 display:block 和 text-align:center 但这似乎没有效果。

HTML:

<div class="row services">

    <div class="col s12 l3">
        <div class="divider"></div>
        <h5><p>Nelson Mazda Tulsa</p> <p>Tulsa, OK</p></h5>
        <p>9902 S. Memorial Dr.</p>
        <p>Tulsa, OK 74133</p>

CSS:

Answer 1

使用 CSS Flexbox 可以轻松居中。

这就是你所需要的:

.row {
    display: flex;
    flex-direction: column;
    align-items: center;
}
