bootstrap responsive image

<img src="..." class="img-fluid" alt="Responsive image">

<img class="img-fluid" src="" alt=""> //This will make your image responsive

If you are using the <picture> element to specify multiple <source> elements for a specific <img>, make sure to add the .img-* classes to the <img> and not to the <picture> tag.


<picture>
  <source srcset="..." type="image/svg+xml">
  <img src="..." class="img-fluid img-thumbnail" alt="...">
</picture>
