Alloy UI has combined HyperText Markup Language 5 (HTML5), Cascading Style Sheets Level 3 (CSS3), and Yahoo! User Interface Version 3 (YUI3). It has been constructed with Liferay's best view practices. Alloy UI is robust and flexible.
Alloy UI uses markup as defined in HTML5 for structuring of a page. It applies CSS3 style to Document Object Models (DOM). For the dynamic behavior on a portal page, Alloy UI employs YUI3.
On its website http://alloy.liferay.com/, there are demos that show image gallery, autocomplete, color picking, and live search.
Alloy UI library is an independent package. It is not tied to Liferay. A developer is encouraged to use it in other web applications.
