You may or may not be familiar with Lightbox, a handy JavaScript library that lets you create very slick interactive image galleries very easily with plain old HTML and a little elbow grease. Lightbox is great, but not exactly svelte, weighing in at just over 100kb not including images. If that's a little hefty for your taste, check out Litebox, a drop-in replacement for Lightbox that looks like it and works like it but weighs in at less than 30kb. It pulls it off by swapping in the lightweight moo.fx which creates the same effects as Lightbox has but at a lower price. Like the original Lightbox, Litebox is free and easy to set up.
