Q.What is the difference between Named skins and Default skins?
A. default skin automatically applies to all controls of the same type when a theme is
applied to a page. A control skin is a default skin if it does not have a SkinID attribute.
For example, if you create a default skin for a Calendar control, the control skin applies
to all Calendar controls on pages that use the theme. (Default skins are matched exactly
by control type, so that a Button control skin applies to all Button controls, but not to
LinkButton controls or to controls that derive from the Button object.)

A named skin is a control skin with a SkinID property set. Named skins do not
automatically apply to controls by type. Instead, you explicitly apply a named skin to a
control by setting the control's SkinID property. Creating named skins allows you to set
different skins for different instances of the same control in an application.

application?

@page directive

2.At the application level-can be applied to all pages in an
application by setting the element in the application configuration
file.

3.At the web server level-Define the element in the machine.config

Q.What is a "theme" in ASP.NET?
A. A "theme" is a collection of property settings that allow you to define the look of pages
and controls, and then apply the look consistently across pages in a Web application,
across an entire Web application, or across all Web applications on a server.

Web sites on the same server.

Q.What is the difference between themes and CSS?

A. 1. Themes can define many properties of a control or page, not just style properties. For
example, using themes, you can specify the graphics for a TreeView control, the template
layout of a GridView control, and so on.

2. Themes can include graphics.

3. Themes do not cascade the way style sheets do. By default, any property values
defined in a theme referenced by a page's Theme property override the property
values declaratively set on a control, unless you explicitly apply the theme using the
StyleSheetTheme property.
