Question

I’m trying to do some experimental stuff for which YUI looks like the best solution. The Getting Started documentation is all written on the assumption that you already know how to use YUI and only need to find out how to use specific components. Is there any documentation available that tells you how to go from an empty public_html directory to some kind of Hello World equivalent in YUI (preferably version 3)?

Answer 1

YUI is used like you would use any javascript: you need to include the relevant js files in the head section of your html and then write some javascript to tie them together (call the yui methods).

The page source for the simplest yui button example
http://developer.yahoo.com/yui/examples/button/btn_example01_clean.html
is probably the best place to start: shows how the head section would look like and what you can do with the button.
