jqt
A low-level jQuery plugin for node hiding / showing through css transitions.
Think of it as a low-level version of builtin jQuery animations such as $.fadeOut, $.fadeIn, $.slideUp, and $.slideDown but with css classes. Or maybe something similar to ng-animate or ReactCSSTransitionGroup for single elements in jQuery.
Use case
I've never found any similar libraries outside frameworks. This library was massively dogfed for projects I handle at work, usually for tab transitions, menu animations, etc.
