Utilize Bootstrap to resize an image to fit within a div container

My goal is to have images in a carousel fill the entire width and height of the containing div. Currently, the images do not occupy 100% of the width of the div and the height varies. I am working with Bootstrap 4.3.1. Here is an excerpt of my code:

<div class="row">

    <!-- card 1 -->
    <div class="col-sm-4 card" style="height: 350px">
        <div class="card-body small-tab-container>
            <h6 class="card-title">Activity (last 7 days)</h6>

            <p>Some content</p>

        </div>

    </div> <!-- end card 1 -->

    <!-- card 2 -->
    <div class="col-sm-4 card" style="height: 350px;">
        <div id="photoCarousel" class="carousel slide" data-ride="carousel">
            <div class="carousel-inner">

                 <div class="carousel-item active">
                    <img src="https://media.wired.com/photos/5fb70f2ce7b75db783b7012c/master/pass/Gear-Photos-597589287.jpg" class="d-block img-fluid">
                </div>

                <div class="carousel-item">
                   <img src="https://images.pexels.com/photos/3680219/pexels-photo-3680219.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500" class="d-block img-fluid">
                </div>

               <div class="carousel-item">
                    <img src="https://www.cnet.com/a/img/-qQkzFVyOPEoBRS7K5kKS0GFDvk=/940x0/2020/04/16/7d6d8ed2-e10c-4f91-b2dd-74fae951c6d8/bazaart-edit-app.jpg" class="d-block img-fluid">

                    <span class="sr-only">Previous</span>
                </a>

                <a class="carousel-control-next" href="#photoCarousel" 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> <!-- end card 2 -->

    <!-- card 3 -->
    <div class="col-sm-4 card" style="Height: 350px">
        <div class="card-body small-tab-container">
            <h6 class="card-title">Upcoming Events</h6>


            <p>Some content</p>

        </div>
    </div> <!-- end card 3-->

</div> <!-- end: row 1 -->

Answer №1

The default padding of your card <div> elements is still in place,

To remove the padding, switch all instances of 

<div class="col-sm-4 card" ...>
to 
<div class="col-sm-4 card p-0" ....>
.

Alternatively, you can update the appropriate classes to include padding: 0;

Answer №2

By utilizing CSS properties like object-fit and object-position on the images, along with incorporating additional bootstrap classes, I've successfully achieved a layout where your images occupy 100% of the height and width within the carousel container. Does this meet your desired outcome?

.carousel-item img {
  object-fit: cover;
  object-position: center center;
}
<!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
