Question

我的旋转木马尺寸为1200 * 500。当我放置一个相同尺寸的图像时，它没有占据旋转木马的整个宽度，只是部分。

我尝试使用＆＃34; fill＆＃34;我的HTML代码中的类但它不起作用，我也试过这个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">

                    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
                    <li data-target="#carousel-example-generic" data-slide-to="2"></li>

我为你做了this example（这有点简单，但会帮助你）。

与您的相比，我所做的更改是，我现在将图像添加为DIV中的背景，而不是图像元素。因此，无论图像的大小如何，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="carousel-caption">

    </div>
  </div>
