Slimbox is a 4 kb visual clone of the popular lightbox 2 script by lokesh dhakar, written using the jquery javascript library (in version 2) or the mootools javascript framework (in version 1). it was designed to be very small, efficient, standards-friendly, fully customizable, more convenient and 100% compatible with the original lightbox 2.

although the design and base functionalities are the same as lightbox, the code was written from scratch and is constantly improved.
