The majority of web image galleries must load at least two copies of every photo: a small thumbnail and a full-size version. While this approach has its advantages, it has an equal number of annoyances and drawbacks.

My recent exploration of object-fit led me to experiment with using the property to improve image galleries, inspired by the work of Chris Mills. The only downside is that the thumbnail images will appear squished in browsers that do not yet support the property (Firefox and IE).

A simple example is the bouncing ball at the top of this article, the motion of which might be used to notify the user to a vital alert message. The markup is a single <div> element, styled and shaped to resemble a ball:
