bootstrap 4 img-fluid does not change image height

Question

Responsive Images in Bootstrap 4, with class .img-fluid are resized disproportionally. They keep it's height even width is shrinking down correctly. That is deforming whole image. Is there any way how to make it as smooth as it was in Bootstrap 3 with class .img-responsive? Thanks

<div class="col-sm-6">
    <img class="img-fluid" src="/assets/blogs/14853991244821.jpg" alt="">
</div>

By the way it is same in Bootstrap 4 documentation (https://v4-alpha.getbootstrap.com/content/images/) where sample svg image keeps height 250 pixels regardless of it's width.

Answer 1

The problem was I wrapped image in div with class .row which have display property set to flex. once removed this class from parent div image working as expected
