如何将我的背景制作成自动幻灯片/轮播？

Question

我想一次放 5 张图片作为页面的背景，即一张图片会显示一小段时间（比如说每张一秒钟），然后重复它们。

我想知道是否有办法用 CSS 或 JS 做到这一点？

在此先感谢您的帮助！

问题解决了。 这很容易。 你可以在这里找到源代码。

使用 Bootstrap 创建全屏背景滑块

HTML：

<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">

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

        <!-- Wrapper for slides -->
        <div class="carousel-inner" role="listbox">
            <div class="item active">  
                <div class="carousel-caption">
                  <h3>First slide label</h3>
                  <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
                </div>
            </div>
            <div class="item"> 
                <div class="carousel-caption">
                  <h3>Second slide label</h3>
                  <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
                </div>
            </div>
            <div class="item"> 
                <div class="carousel-caption">
                  <h3>Third slide label</h3>
                  <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
                </div>
            </div>
        </div>
    </div>
