Letterbox

View source on GitHub

Letterboxes are useful if you have some source media which is larger than
the area you want to display it in. For instance, you might have a really
tall image and want it to be displayed in a neatly cropped square. While the
ideal solution to this problem is to update the source image, this might not
always be possible for either cost or performance reasons.

Letterbox should be used in situations where you would otherwise use the
CSS property background-size: cover.
