The jQuery Catfish Plugin allows you to display Catfish adverts with one simple function call.
Catfish adverts are adverts that appear in a seperate section to the content on a page. They attract the attention of the eye very easily when they slide in. As well as adverts you can place any other sort of content possible in there. Anything that can go in a DIV can be used. Normally you have to apply many CSS hacks to make it work in all browsers (IE is the problem) but this is only 1 function call and the work is done. Makes life so much easier.
There are also a few options you can set to customise how the Catfish will show up.
As for the name it’s something I got off the original inventer, Sitepoint. It means “creature that sucks the bottom”
