Default Skin & Named Skin

Skins

Generally, Themes contain skins. A skin file contains style definitions for the individual server controls. You can define skin settings for a control using similar markup which we use to add server controls to web page. Only difference you may find between skinned versions of control is that skinned version do not include ID attribute for control. You should retain properties for which you want to configure through Themes. We create .skin files in Theme folder. We can also mix all server controls style definition in a single skin file. Make sure all style definition files like CSS, skin files, Image files and other resources are included in Themes folder in your application directory.

<asp:button runat="server" BackColor="lightblue" BorderColor="AliceBlue" Font-Bold ="true" ForeColor="black"/>
Skin file

There are two types of control skins based on their scope. They are:

Default Skins: Control skin for which SkinID attribute is not set which means control skin is applied automatically for the controls of same type. For example: if you create a default skin for button then default button control skin will be applied for all the buttons on the page. The scope of default skin depends on where you define default skin.

Named Skins: Named Skins will have SkinID property set which means you can use named skins with a control only by setting control's SkinID property to specific named skinID. Named Skins do not apply for the controls by type.
