将 Bootstrap4 Carousel-item 一分为二

Question

大家好，我想把每张幻灯片一分为二，一张图片，一张描述，看图。这是一个引导程序 4，我没有找到任何解决方案，我只是找到了对我不起作用的引导程序 3 的示例。

我用了简单的网格<div class="col-lg-6">但是没有用，只是在图片下面推了描述。

谢谢！

Picture - Something like this

<div id="demo" class="carousel slide" data-ride="carousel">
  <!-- The slideshow -->
  <div class="carousel-inner">
    <div class="carousel-item active">
        <div class="col-lg-6"> 
          <img src="http://lorempixel.com/400/200/" alt="Los Angeles" width="400" height="200">
        </div>
        <div class="col-lg-6"> 
          <h3>Firste caption</h3>
          <p>Loren ipsun</p>
        </div>
    </div>
    <div class="carousel-item ">
        <div class="col-lg-6"> 
          <img src="http://lorempixel.com/400/200/" alt="Los Angeles" width="400" height="200">
        </div>
        <div class="col-lg-6"> 
          <h3>Firste caption</h3>
          <p>Loren ipsun</p>
        </div>
    </div>
    <div class="carousel-item ">
        <div class="col-lg-6"> 
          <img src="http://lorempixel.com/400/200/" alt="Los Angeles" width="400" height="200">
        </div>
        <div class="col-lg-6"> 
          <h3>Firste caption</h3>
          <p>Loren ipsun</p>
        </div>
    </div>
  </div>
</div>

Answer 1

将.rows 放在.carousel-items 中，将.col-*s 放在.rows 中。像这样：

...
<div class="carousel-item ">
  <div class="row">
    <div class="col-lg-6"> 
      <img src="http://lorempixel.com/400/200/" alt="Los Angeles" width="400" height="200">
    </div>
    <div class="col-lg-6"> 
      <h3>Firste caption</h3>
      <p>Loren ipsun</p>
    </div>
  </div>
</div>
...

如果您希望轮播以较低的宽度保持分割，您可能希望将col-lg-6 与col-md-6、col-sm-6 甚至col-6 交换（这在 v4 中意味着它将在所有宽度上保持分割）。

这是一个例子：

.carousel-item {
  background-color: #424242;
  color: white;
  min-height: 220px;
}
