Bootstrap 4 Grid Row - Images Not Aligning Vertically

Question

I have a row of images that for some reason aren't aligning vertically. If I use all the same images, it looks fine, but if I replace with a different image with slightly different dimensions it doesn't work. Here's an example below:

Here's my HTML code..note I am using some custom CSS for an overlay, not sure if that could be causing a problem

<div className="container">

          <div className="row">

            <div className="col-xl-12 mx-auto mb-3">
              <h2 className="abouthead">Portfolio</h2>
            </div>
          </div>
          <div className="row">
            <div className="col-lg-4 col-md-12 mb-4">
              <div
                className="view overlay hm-black-strong"
                data-toggle="modal"
                data-target="#modal1"
              >
                <img
                  src="http://localhost:3002/images/dealmazing.JPG"
                  className="img-fluid"
                  alt="sample"
                />
                <div className="p-2 bg-info text-white">Deals Website</div>
                <div className="mask flex-center">
                  <p className="white-text">View Project</p>
                </div>
              </div>
            </div>

            <div className="col-lg-4 col-md-12 mb-4">
              <div
                className="view overlay hm-black-strong"
                data-toggle="modal"
                data-target="#modal2"
              >
                <img
                  src="http://localhost:3002/images/crypto-portal.JPG"
                  className="img-fluid"
                  alt="sample"
                />
                <div className="p-2 bg-info text-white">
                  Cryptocurrency Portal
                </div>
                <div className="mask flex-center">
                  <p className="white-text">View Project</p>
                </div>
              </div>
            </div>

            <div className="col-lg-4 col-md-12 mb-4">
              <div className="view overlay hm-black-strong">
                <img
                  src="http://localhost:3002/images/dealmazing.JPG"
                  className="img-fluid"
                  alt="sample"
                />
                <div className="p-2 bg-info text-white">Deals Website</div>
                <div className="mask flex-center">
                  <p className="white-text">View Project</p>
                </div>
              </div>
            </div>

            </div>

Answer 1

Have you tried specifying a height for your image? And then apply Object-Fit CSS property.

img {
  object-fit: cover;  
  width: 400px;
  height: 400px;  
}
