Here is the code that I am currently working with:
<div class="col-sm-4">
<div class="card">
<div class="card-block">
<div class="col-sm-4">
<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" role="listbox">
<div class="carousel-item active">
<img class="d-block img-fluid"
src="http://www.public-domain-photos.com/free-cliparts-4/computer/actions/ok.png"
alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block img-fluid" src="https://k36.kn3.net/CA1AEE661.jpg"
alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block img-fluid"
src="http://www.public-domain-photos.com/free-cliparts-4/computer/actions/ok.png"
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">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>
</div>
</div>
</div>
</div>
I have selected three random images as examples. Although their resolution is higher, they appear smaller in my project.
Whenever I attempt to create my own CSS class instead of using col-sm-4, the carousel functionality ceases to work.
How can I adjust the size of the carousel?
