jQuery UI 是一套 jQuery 的页面 UI 插件，包含很多种常用的页面空间，例如 Tabs（如本站首页右上角部分） 、拉帘效果（本站首页左上角）、对话框、拖放效果、日期选择、颜色选择、数据排序、窗体大小调整等等非常多的内容。
jQuery UI provides abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets, built on top of the jQuery ">JavaScript Library, that you can use to build highly interactive web applications.
