Telerik provides 23 embedded skins in our Telerik.Web.UI.Skins assembly. The skin appearance of the used controls is of high importance for everyone. Telerik is providing not only more than 20 skins, but also created an online tool for point-and-click generation of custom skins for RadControls for ASP.NET AJAX. So using Telerik style builder
to customize the skin for the controls is a suggested approach from Telerik for creating a new skin from the existing skin as a template.
