Physical UI Layer

---

The physical user interface (UI) consists of the physical files, templates, Siebel tags, style sheets, and other file-based metadata that control the layout (as opposed to the content) of the user interface (for example, CSS, SWF, and GIF files). The Applet Web Template, Applet Web Template Item, View Web Template, View Web Template Item objects are part of the logical UI layer; their object definitions are stored in the Siebel repository. Examples of physical UI objects are:

• Templates files. A Siebel template is a special kind of HTML file that defines the layout and formatting of elements of the user interface (such as views, applets, and controls). It provides this layout information to the Siebel Web Engine when rendering Siebel objects in the repository to HTML files.

  The layout and style of HTML Web pages is dynamic, which allows simultaneous support for multiple browser types and versions. This is accomplished through the conditional branching in Web templates.

• Tags. Siebel tags are special tags you insert into template files. They specify how Siebel objects defined in the repository should be laid out and formatted in the final HTML page in the user's Web browser.

  The process of configuring a Web application separates the layout and formatting from the application definition and binding to data. You use Siebel tags to map objects into a HTML physical layout.

• CSS. Siebel Cascading Style Sheets are external style sheet documents (of type text/CSS) to define how HTML or XML elements and their contents should appear in a Web document.

  CSS provide rules for resolving conflicts in HTML or XML These rules consist of two main parts: a selector and a declaration. The declaration has two parts: property and value.
