css - Bootstrap 轮播内部图像

Question

我的旋转木马是一个 1200*500 尺寸的旋转木马。当我放置相同尺寸的图像时，它不会占用轮播的整个宽度，只是部分宽度。

我尝试在我的 html 代码中使用“fill”类，但它不起作用，我也尝试使用这个 css 代码:

 .carousel,
 .item,
 .active {
    height: 100%;
}

  .carousel-inner {
    height: 100%;
} 

似乎没有任何效果。请帮忙

HTML代码:

<div class="container">
    <div class="row">
        <div class="col-md-12">
            <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
                <ol class="carousel-indicators">
                    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
                    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
                    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
                </ol>
                <div class="carousel-inner">

我做了this example适合您(这有点简单，但会帮助您)。

与您的相比，我所做的更改是我现在将图像作为背景添加到 DIV 中，而不是图像元素中。因此，无论图像大小如何，我们都可以控制显示。

.carousel-img {
  width: 100%;
  height: 400px;
  background-size: cover;
}

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
      <div class="carousel-img" style="background-image: url('http://lorempixel.com/1200/500/')"></div>
      <div class="carousel-caption">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
      </div>
    </div>
    <div class="item">
      <div class="carousel-img" style="background-image: url('http://lorempixel.com/1200/500/')"></div>
      <div class="carousel-caption">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
      </div>
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
