The Visual Style Builder is a tool that can be used to create the base of custom skins for the Classic rendering of Telerik controls. It provides an interactive UI that helps in customizing the appearance of the skin. It can be found at http://stylebuilder.telerik.com/.
For everyone who wants to create an customize skins for the modern Lightweight rendering of the components, we recommend using the Telerik Theme Builder.
The main features of the Visual Style Builder are:
Changing the main color of an existing skin with just a few clicks
Modifying the skin for one control only or for a set of controls
Fine tuning individual elements in the control, e.g. fonts, backgrounds, paddings
Editing an already existing skin that can be uploaded as an archive
