Question

我正在使用引导程序4编写代码。在轮播图像上，应该有另一个图像（底部是一个漂亮的图层），但是下面的代码不是出现在图片的底部，而是下面的代码。也许您对如何解决这个问题有任何想法？

HTML

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
        <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
        <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
        <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img class="d-block w-100" src="img.img1.jpg" alt="First slide">
            <img class="ex-img" src="img/img2.jpg" alt="orange-img">
        </div>
        <div class="carousel-item">
            <img class="d-block w-100" src="img/img2.jpg" alt="Second slide">
            <img class="ex-img" src="img/img4.jpg" alt="orange-img">
        </div>
        <div class="carousel-item">
            <img class="d-block w-100" src="img/img5.jpg" alt="Third slide">
            <img class="ex-img" src="img/img6.jpg" alt="orange-img">
        </div>
        <a class="carousel-control-prev" href="#carouselExampleIndicators" 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="#carouselExampleIndicators" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>
</div>

CSS

.carousel .slide{
position:absolute;
}

.carousel-item img{
position:relative;
}

.ex-img{
position:relative;
}

我不确定您的意思，但是尝试更改如下样式

L = ['A', 'Z', 'Z', 'A', 'C', 'Z']

df1 = pd.DataFrame({'company':L})
df1['g'] = df1.groupby('company').cumcount()
df['g'] = df.groupby('company').cumcount()

df = df1.merge(df)
print (df)
  company  g  col1  col2  col3
0       A  0     0   130     0
1       Z  0     0     0   150
2       Z  1     0     0   140
3       A  1     0   145     0
4       C  0   173     0     0
5       Z  2     0     0   110

Bootstrap 4轮播图像不覆盖其他图像
