如何将 Owl 轮播中的图像居中

Question

我的Owl轮播包含不同宽度和高度的图片。我如何在中间对齐它们 - 水平和垂直？

$("#owl-example").owlCarousel({
  navigation: true
});

Answer 1

Owl 轮播在您的布局中创建额外的块。要正确添加 CSS 属性，您需要使用此 HTML 结构：

<div id="owl-demo" class="owl-carousel owl-theme">
  <div class="owl-wrapper-outer">
    <div class="owl-wrapper">
      <div class="owl-item">
        <div>
          <img src="" alt="">
        </div>
      </div>
      <div class="owl-item">
        <div>
          <img src="" alt="">
        </div>
      </div>
    </div>
  </div>
</div>

此外，轮播为所有块添加了一个 style 属性。例如，具有 .owl-wrapper class 的块接收值为 block 的 display 属性。所以你必须在 CSS.
中使用 !important 声明
要获得水平对齐，您只需将 text-align: center; 属性添加到每个 .owl-item > div.
要垂直对齐，您可以转动 table 单元格中的轮播项目。但是别忘了为他们取消float属性

让我们将所有更改安排为一个新的 .owl-centered class。请检查结果：

}
.owl-centered .owl-item {

.owl-centered .owl-item > div {

Answer 2

使用 owl 轮播版本 2.1.1 和 CSS3 Flexbox，只需添加样式：

.owl-carousel .owl-stage {
  display: flex;
  align-items: center;
}

查看代码片段：

$( document ).ready( function() {
  $( '.owl-carousel' ).owlCarousel({
     autoplay: true,
     margin: 2,
     loop: true,
     responsive: {
        0: {
           items:1
        },
        200: {
           items:3
        },
        500: {
           items:4
        }
     }
  });
});

.owl-carousel .owl-stage {
  display: flex;
  align-items: center;
}

.owl-carousel .caption {
  text-align: center;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/assets/owl.carousel.min.css" rel="stylesheet"/>

<div class="owl-carousel">
    <div class="item">
      <img src="https://via.placeholder.com/350x200/?text=1">
      <div class="caption">Caption 1</div>
    </div>
    <div class="item">
      <img src="https://via.placeholder.com/255x200/?text=2">
      <div class="caption">Caption 2</div>
    </div>
    <div class="item">
      <img src="https://via.placeholder.com/627x200/?text=3">
      <div class="caption">Caption 3</div>
    </div>
    <div class="item">
      <img src="https://via.placeholder.com/627x300/?text=4">
      <div class="caption">Caption 4</div>
    </div>
    <div class="item">
      <img src="https://via.placeholder.com/627x400/?text=5">
      <div class="caption">Caption 5</div>
    </div>
    <div class="item">
      <img src="https://via.placeholder.com/255x200/?text=6">
      <div class="caption">Caption 6</div>

Answer 3

这对我有用：

@media (max-width:500px) {
    .owl-carousel .owl-item {
        text-align:center;
    }
    .owl-carousel .item {
        float: none;
        display: inline-block;
    }
}

虽然您可以将其调整为您的 HTML，但想法是您文本对齐父项，float:none 和 display:inline-阻止包含内容的子项, 在手机上：

Answer 4

显示 table 的解决方案是可以的，但对我来说，右侧和左侧的 div 从容器中滑出。我的代码几乎相同，我将 table 和 table-cell 更改为 block 和 inline-block

.owl-stage{
  display: block !important;
}

.owl-item{
  display: inline-block;
  float: none;
  vertical-align: middle;
}

.item{
  text-align: center;
}

结果（所有图片大小不同）：

Answer 5

另一种解决方案是使用带边距的 flexbox。

.owl-stage-outer {
  display: flex;
  flex-wrap: nowrap;
  flex-direction: column;
}
.owl-stage-outer > .owl-stage {
  margin:0 auto;
}

Answer 6

我建议这个解决方案：

.owl-carousel .owl-stage {
    margin: 0 auto; 
}
