Bootstrap Carousel图像不以全宽显示

Question

我正在使用Bootstrap 3 创建一个简单的HTML模板.我检查中等大小的模板,看起来没问题.但是当我在更大的显示器(和更高的分辨率)中检查它时,我在转盘内的图像的右侧看到一些空白区域.

    <div id="myCarousel" class="carousel slide" data-ride="carousel">

        <span class="glyphicon glyphicon-chevron-left">
        </span>
      </a>
      <a class="right carousel-control" href="#myCarousel" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right">
        </span>
      </a>
    </div>
    <!-- end #mycarousel -->

如何解决这个问题？

我试着在Carousel类之前插入容器类,但是没有给我全宽旋转木马.我希望Carousel全宽,不要用容器类宽度包装.

Answer 1

在你的CSS

.carousel-inner>.item>img, .carousel-inner>.item>a>img {
display: block;
height: auto;
max-width: 100%;
line-height: 1;
width: 100%; // Add this
}

Answer 2

这是因为 bootstrap 没有将 crousel 内容对齐到中心

你有2个选择

1.修改CSS并居中对齐

.carousel-inner > .item > img, .carousel-inner > .item > a > img {
    display: block;
    height: auto;
    line-height: 1;
    margin: 0 auto;
    max-width: 100%;
}

2.不要在div中使用背景图像，例如

   <div class="item">
       <div style="background-image: url(img/4.jpg); height: 400px;background-size: contain; margin: 0px auto; width: 95%;">
       </div>
   </div>
