Page Contents

Responsive Images

Images can be made to scale with their container width by using .img-fluid. This applies max-width: 100%; and height: auto; the image, allowing the aspect ratio to be maintained.

SVG Images and IE 10

In Internet Explorer 10, SVG images with .img-fluid are disproportionately sized. To fix this, add width: 100% \9; where necessary. This fix improperly sizes other image formats, so we do not apply it automatically.

Image Thumbnail

Use .img-thumbnail to give an image a bordered appearance.

You might also want to check the border utilites for additional options.

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

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.
