Question

我试图在顶部使用自举轮播进行视差效果。我想用内容覆盖它。

这是我现在没有视差的代码。

.content{
  width: 100%;
  height: 500px;
  background-color: brown;
  color: white;
}

我已经尝试了很多事情。我无法使用backgroung-img，然后将其修复，因为Iam使用了动态渲染对象。我当时在考虑z-index和相对位置的关系，但是那对我也不起作用。

CSS：

.carousel-inner {
  position: relative;
}

.content{
  width: 100%;
  position: absolute;
  top: 0;
  left: 0;
  z-index: 1;
}

.content p {
  color: #FF8000;
}

.carousel-control-next, .carousel-control-prev {
  z-index: 2;
}

我进行了一些颜色更改，以使文本和轮播指示器更加可见。

Answer 2

因此，经过漫长的思考，我找到了解决方案。

使用

<div class="carousel-item active">
  <img class="d-block w-100 img-fluid" src="${blok.get_obrazek_url(site)}">
</div>

我是这样做的

 <div class="carousel-item active">
   <div class="carousel-image " style="background-image:url('${blok.get_obrazek_url(site)}');"></div>    
 </div>

，此后，我可以在css文件中使用背景附加。
