A skin is a set of images and a CSS stylesheets that are applied to the HTML elements which make up the share bar and popup, defining the look and feel. To apply a skin, set the Skin property of the RadSocialShare. You can do so by using the properties pane, the server-side property or the control's Smart Tag.
RadSocialShare is installed with a number of predefined skins:
The Material skin is available for the Lightweight RenderMode only. If you experience visual issues with it, make sure your controls are not using the default Classic mode.
