<div class = "container">

<div class = "card" style = "width: 100%;">
  <img class = "card-img-top" src = "http://getbootstrap.com/docs/4.1/assets/brand/bootstrap-social.png" alt = "Card image cap">
  <div class = "card-body">
    <h5 class = "card-title">Card title</h5>
    <p class = "card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
    <a href = "#" class = "btn btn-primary">Go somewhere</a>
  </div>
</div>
</div>
<div>
I need this text to be underneath the card.I tried using margin-bottom for the card, but the problem with this is the content of the card body changed, therefore the height changes which is what i want.
