Yahoo! User Interface Library

The Yahoo! User Interface (YUI) Library is a rich set of utilities and controls, written in JavaScript. It is used for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources.

The YUI Library components fall into three groups: Utilities, UI Controls, and CSS resources.

YUI Utilities

The YUI Utilities simplify in-browser devolvement that relies on cross-browser DOM scripting, as do all web applications with DHTML and AJAX characteristics. Various utilities are:

• Event
• Dom Collection
• Connection Manager
• Drag & Drop
• Animation

YUI Controls

The YUI Library Controls provide highly interactive visual design elements for your web pages. These elements are created and managed entirely on the client side and never require a page refresh.

YUI Controls include:

• AutoComplete
• Container
• DataTable Control
• Logger
• TabView
• TreeView
• Slider
• Calendar

YUI CSS Resources

• CSS Grids
• CSS Fonts
• CSS Reset
