未学习JS也可以通过bootstrap做出轮播图的实际应用

<div class="col-md-9 lunbo"><br />    <div id="carousel-example-generic" class="carousel slide" data-ride="carousel" style="margin-top: 1.4285rem"><br />        <!-- Indicators --><br />        <ol class="carousel-indicators" style="margin-left: -20rem"><br />            <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>     这里规定播放顺序 3个li代表3个小点 点一个小点 就是一张图<br />            <li data-target="#carousel-example-generic" data-slide-to="1"></li><br />            <li data-target="#carousel-example-generic" data-slide-to="2"></li><br />        </ol><br /><br />        <!-- Wrapper for slides --><br />        <div class="carousel-inner"> 这里是要播放的图 3张<br />            <div class="item active">这里的active 对应上面active的那个小圆点<br />                <img src="三组项目/PC/PC首页/lunbo1.jpg" alt="..."   style="max-width:90%"><br />                <div class="carousel-caption"></div><br />            </div><br />            <div class="item"><br />                <img src="三组项目/PC/PC首页/lunbo2.jpg" alt="..."  style="max-width:90%"><br />                <div class="carousel-caption"></div><br />            </div><br />            <div class="item"><br />                <img src="三组项目/PC/PC首页/lunbo3.jpg" alt="..."  style="max-width:90%"><br />                <div class="carousel-caption"></div><br />            </div><br />        </div><br /><br />        <!-- Controls -->   这里就是那左右两个箭头<br />        <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">上翻<br />            <span class="glyphicon glyphicon-chevron-left"></span><br />        </a><br />        <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">下翻<br />            <span class="glyphicon glyphicon-chevron-right"></span><br />        </a><br />    </div><br /></div>

data-slide-to="0" 里面的数字  这里的0 只是举例数字  具体情况 自行判断
