Responsive images

Resolution switching

If you suport multiple display resolutions and want to display larger or smaller images depending on the device, use <img> tag with scrset and/or sizes atributes:

Width based example image


Screen density example image

Picture element

Use for:

  • Art direction (ex: loading a simpler version of an image, on smaller displays).
  • Offering alternative image formats.
  • Saving bandwidth and speeding page load times by loading the most appropriate image for the viewer's display.

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.
