Images

Responsive imagesLink to this section: Responsive images

Images in Boosted are made responsive with .img-fluid. This applies max-width: 100%; and height: auto; to the image so that it scales with the parent width.

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

Image thumbnailsLink to this section: Image thumbnails

In addition to our border-radius utilities, you can use .img-thumbnail to give an image a 2px border appearance.

<img src="..." class="img-thumbnail" alt="...">

Aligning imagesLink to this section: Aligning images

Align images with the helper float classes or text alignment classes. block-level images can be centered using the .mx-auto margin utility class.

<img src="..." class="float-start" alt="...">
<img src="..." class="float-end" alt="...">

<img src="..." class="mx-auto d-block" alt="...">

<div class="text-center">
  <img src="..." alt="...">
</div>

PictureLink to this section: Picture

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="...">
