Bootstrap4 轮播

轮播是一个循环的幻灯片:


如何创建轮播

以下实例创建了一个简单的图片轮播效果 :

实例

<div id="demo" class="carousel slide" data-ride="carousel"> <!-- 指示符 --> <ul class="carousel-indicators"> <li data-target="#demo" data-slide-to="0" class="active"></li> <li data-target="#demo" data-slide-to="1"></li> <li data-target="#demo" data-slide-to="2"></li> </ul> <!-- 轮播图片 --> <div class="carousel-inner"> <div class="carousel-item active"> <img src="https://static.zyiz.net/images/mix/img_fjords_wide.jpg"> </div> <div class="carousel-item"> <img src="https://static.zyiz.net/images/mix/img_nature_wide.jpg"> </div> <div class="carousel-item"> <img src="https://static.zyiz.net/images/mix/img_mountains_wide.jpg"> </div> </div> <!-- 左右切换按钮 --> <a class="carousel-control-prev" href="#demo" data-slide="prev"> <span class="carousel-control-prev-icon"></span> </a> <a class="carousel-control-next" href="#demo" data-slide="next"> <span class="carousel-control-next-icon"></span> </a> </div>


轮播图片上添加描述

在每个 <div class="carousel-item"> 内添加 <div class="carousel-caption"> 来设置轮播图片的描述文本::

实例

<div class="carousel-item"> <img src="https://static.zyiz.net/images/mix/img_fjords_wide.jpg"> <div class="carousel-caption"> <h3>第一张图片描述标题</h3> <p>描述文字!</p> </div> </div>
