Question

我需要在Bootstap4的基本滑块下面放置一个标题。
这是我的HTML代码

<div class="col-xs-12 col-sm-6 col-md-5" style="float:right; padding:0;">
    <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
        <div class="carousel-inner">
            <div class="carousel-item active">
                <img class="d-block w-100" src="images/1.jpg" alt="First slide">
                <div class="newcaption">
                    <p>First caption</p>
                </div>
            </div>
            <div class="carousel-item">
                <img class="d-block w-100" src="images/2.jpg" alt="Second slide">
                <div class="newcaption">
                    <p>Second caption</p>
                </div>
            </div>
            <div class="carousel-item">
                <img class="d-block w-100" src="images/3.jpg" alt="Third slide">
                <div class="newcaption">
                    <p>Third caption</p>
                </div>
            </div>
        </div>


        <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>  
</div>

首先，我的css是

.carousel-inner{position:relative; width:100%; overflow:hidden;}
.newcaption{position:absolute; bottom:-25px; top:auto; color:#000;}

然后它就像这样

（Sory，我的声誉不足以发布图片。）

然后我改变溢出：＆＃34;隐藏＆＃34;到＆＃34;可见＆＃34;在.carousel-inner。现在它工作，但它显示2个图像，而改变这样的图像

那么如何在此问题中定位标题？

请参阅使用以下代码的css，运行代码段并检查结果。

＆＃13;

.carousel-inner{position:relative; width:100%; overflow:hidden}
.newcaption{position:absolute; bottom:5px; top:auto; color:#000; left:5px}
.newcaption p{ margin:0px}
