By applying one of the 20 professionally-designed skins that come with Telerik UI for ASP.NET AJAX, including two engineered with mobile devices in mind, you save design and front-end development time. No need to be a CSS wizard to create or customize the Telerik skins with our web-based Visual Style Builder.
