Align link to bottom of card in Bootstrap 4 [duplicate]

Answer 1

An alternative solution

You can align the link at the bottom of the card-body by following these three steps:

1. Apply the d-flex and flex-column classes to card-body
2. Wrap all the content of card-body in a div.
3. Use flex: 1 1 auto on this new div

Doing so, the newly created div always takes all the available space. Hence, the link is always at the bottom of the card-body.

.flex-grow {
  flex: 1 1 auto;
}

<div class="card-body d-flex flex-column">
  <div class="flex-grow">
    <h4 class="card-title">Project One</h4>
    <p class="card-text">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Amet numquam aspernatur eum quasi sapiente nesciunt? Voluptatibus sit, repellat sequi itaque deserunt, dolores in, nesciunt, illum tempora ex quae? Nihil, dolorem!</p>
  </div>
  <a href="#" class="card-link text-info mt-auto">View CodePen</a>
</div>

FYI, You can make an element occupy all the available space using this method.

Answer 2

The link is placed on the end with d-flex and flex-column on card-body and mt-auto on the link. On your CodePen you are missing some of these classes (example with classes)!

Note: You can find this example also on the official documentation of Bootstrap 4.

To center the links you can use the text-center class on the card-link.
