Bootstrap 4 responsive image with set height

Question

If I have a card inside a column, that needs to have an image with a set height, how do I make it not stretched out, as it currently is in my code example? And without having to have a set width on the image because I want it to be replaceable.

What am I missing and/or doing wrong? Thanks!

 .card-block { padding: 20px; }

 <link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta.2/css/bootstrap.css" rel="stylesheet" /> <div class="col-md-6"> <div class="card"> <img class="card-img-top" src="https://placeimg.com/640/480/animals" alt="Card image cap" height="200"> <div class="card-block text-center"> <p class="card-text">Text goes here</p> <p class="card-subtitle">More text goes here</p> </div> </div> </div>

Answer 1

Your best solution is to instead of placing the image directly onto the page you can create an empty div and then set the background image to be https://placeimg.com/640/480/animals then set its size to cover and then it will cover the height and width of the div you have specified

so for example...

css

 card-image-container{
     background: url('https://placeimg.com/640/480/animals') 50% no-repeat;
     background-size: cover;
 }

Making an image responsive in Bootstrap 4 is very easy:

You just add the img-fluid class to the image.

HOWEVER... responsiveness comes at a cost and that is: You cannot set a minimum height for a responsive image (because that in itself would make the image non-responsive).

Luckily, there are a few workarounds for managing the size of your card image while still keeping it responsive. You can do that by manipulating the horizontal padding (use the px-* class and swap the * for a number between 0 and 5) as well as increasing or decreasing the column width.

Take a look at the 3 examples here:

Usually, when using Bootstrap you should use div with the class of container or container-fluid and after that div with the class of row. This worked for me

<div class="container">
 <div class="row">
  <div class="col-md-6">
   <div class="card">
   <img class="card-img-top" src="https://placeimg.com/640/480/animals" 
    alt="Card image cap" height="200">
   <div class="card-body text-center">
    <p class="card-text">Text goes here</p>
    <p class="card-subtitle">More text goes here</p>
    </div>
   </div>
  </div>
 </div>
</div>

Cards know to be pain in the.. But I hope this helps.
