Various Steps On How To Download YUI
You can get the authentic version of YUI 3.1x on GitHub. There are around three versions that are available there so you can choose the one that.
If you want the jar files for YUI 2.9 or then you can visit “java2s.com”. Not only will you get this version but also from version 0.2 to 1.x. All these are jar files.
If you still want, archived files and documentation for YUI 2, which is no longer in use since 2011, you can visit “https://yui.github.io.”. Here, you can get all the documentation and zip Archives for version 2.2.x to 2.9.0.
I would recommend not using YUI 2 for your project but you can go ahead and search these websites to download the authentication version of YUI.
