如何在父div中居中几个div？

Question

我在父div（class="row services"）中包含3个div。

我怎样才能使三个col s12 l3 div在这个父div中集中居中？

我已尝试使用display:block和text-align:center，但似乎没有效果。

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>

Answer 1

CSS Flexbox可以轻松实现居中。

以下是您所需要的：

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

Answer 2

试试这个：

.col s12 l3{
  margin: 0 auto;
} 

或者如果你想要它们连续：

.col s12 l3 {
 display: inline-block;
}

我希望这就是你要找的东西！
