Bootstrap 4 card/panel with image left of header and title

There are a few different ways you could do this. Here’s one way using the flex-row and flex-wrap utility classes to change the layout of elements inside the card…

   <div class="card flex-row flex-wrap">
        <div class="card-header border-0">
            <img src="//placehold.it/200" alt="" />
        </div>
        <div class="card-block px-2">
            <h4 class="card-title">Title</h4>
            <p class="card-text">Description</p>
            <a href="#" class="btn btn-primary">BUTTON</a>
        </div>
        <div class="w-100"></div>
        <div class="card-footer w-100 text-muted">
            FOOTER
        </div>
    </div>

Here’s another approach using the grid…

  <div class="card">
        <div class="row no-gutters">
            <div class="col-auto">
                <img src="//placehold.it/200" class="img-fluid" alt="">
            </div>
            <div class="col">
                <div class="card-block px-2">
                    <h4 class="card-title">Title</h4>
                    <p class="card-text">Description</p>
                    <a href="#" class="btn btn-primary">BUTTON</a>
                </div>
            </div>
        </div>
        <div class="card-footer w-100 text-muted">
            Footer stating cats are CUTE little animals
        </div>
  </div>

I’m not sure why you have text-center as nothing it centered in the desired example image.
