moo.fx is a superlightweight, ultratiny, megasmall javascript effects library, written with prototype.js.

It’s easy to use, fast, cross-browser, standards compliant, provides controls to modify Height, Width, and Opacity with builtin checks that won’t let a user break the effect with multiple crazy clicks. It’s also optimized to make you write the lesser code possible.

Take a look at the test page, with a comprehensive list of all the effects.

moo.fx has been successfully tested with: Firefox, Safari and Internet Explorer. It should work in most of the gecko browsers too. Only Height and Width will work in Opera, since that browser does not support opacity.

moo.fx is not a replacement for script.aculo.us or other effects libraries. It’s just a little alternative for people (like me) that do not need more than just simple, basic effects (and want to keep their filesize small).
