Question

I want to carousel overlay for Bootstrap 4.1 but .carousel-control-prev-icon and carousel-control-next-icon not working. how can i run icon? Not for each slide element. Just one overlay but over slides.
Below html code;
<!-- Start Banner-->
<section id="banner">
<div class="container-fluid">
<div class="row">
<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="bg-overlay">try fixed overlay</div>
<div class="carousel-item active">
<img class="d-block w-100" src="resources/images/image-1.jpg" alt="image slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" src="resources/images/image-2.jpg" alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" src="resources/images/image-3.jpg" alt="Third slide">
</div>
</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">Önceki</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">Sonraki</span>
</a>
</div>
</div>
</div>
Below css code;
.bg-overlay {
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
top: 0;
right: 0;
width: 100%;
height: 100%;
z-index: 2;
}

Answer 1

In your css file you can overwrite Bootstraps default classes. You can directly target both arrows css to give them a larger z-index value.
Example:
.carousel-control-prev {
left: 0;
z-index: 3;
}
and
.carousel-control-next {
right: 0;
z-index: 3;
}
This will bring the arrows above your overlay and make them clickable.

<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
