Question

我在水平线上有各种图像。有些图像的大小不同，所以我希望所有图像都相对于它们所包含的div居中，所以它看起来更好。我希望在没有当前设置方式的情况下实现这一目标，即添加上边距。

有没有办法在css中自动执行此操作，以便在图像更改时它们仍会相对于包含div居中？

Answer 1

在display: flex和justify-content: center的父级上使用align-items: center会将子级水平和垂直居中放在行中。

如果您没有足够的空间让cols并排显示，并且要将行换行到下一行，请将flex-wrap: wrap应用于.row.centered

＆＃13;

.row.centered {
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
}

＆＃13;

Answer 2

您可以使用flexbox，如下所示：

＆＃13;

.container {
display: flex;
align-items: center;
background-color: grey;
flex-wrap: wrap;
}

.item {
flex-basis: 400px;
flex-grow: 1;
margin: 10px;
height: 200px;
background-color: red;

}

.item1 {
height: 100px;
}

＆＃13;

<div class="container">
<div class="item item1"></div>
<div class="item item2"></div>
<div class="item item13"></div>
</div>

＆＃13;

您可以看到您有一个display属性为flex的容器，以及三个不同高度的弹性项目。

通过将容器的align-items属性（影响垂直对齐）设置为center，您可以将所有弹性项目置于中心位置，无论其高度如何。< / p>

这是一个非常灵活的＆＃34;设计，因为它不依赖于元素的大小或数量。

我希望这会有所帮助。
