While there are some strange redundancies and it’s missing a nice build tool and dependency/include system, I really do like Yahoo UI Library, mostly because it is easy to follow and the basic example widgets are far more refined than other UI libraries.
Here is a link to YUI Cheetsheets in PDF.
I agree Terry. I think the YUI toolkit is a gem in the world of DHTML frameworks.
Other widgets like DojoToolkit are a superset of many YUI features, but I like how YUI just concentrates mostly on UI frameworks. The others have a lot of overhead associated with them.
etc:
