    - Roadmap: Creating and customizing themes
      Theme creation and customization are easy when you use the Theme Manager and download your static theme files by using a WebDAV client. This roadmap provides an overview of the theme creation and customization process. Links to detailed instructions for each step are provided in the roadmap.
    - Getting started with Themes
      Before you begin to develop themes, learn about the resources and the tools you can leverage to create and customize them.
    - The module framework
      The module framework allows extensions to contribute to different areas of a page to provide flexibility, enhance the user experience, and maximize performance.
    - Understanding the Simple Theme
      With the Simple Theme, you can create, copy, and customize themes in minutes with just a few clicks and far fewer files than the Portal 8.5 theme.
    - Understanding the Portal 8.5 modularized theme
      Modern websites and browsers enable incredible new capabilities that can greatly enhance your user's web experiences. However, these capabilities are not without cost in terms of large page sizes and more processing in the browser when each page is rendered. These capabilities are worth it when you need them, but removing them for an entire site or including them only on pages that take advantage of these capabilities provides for more flexibility.
    - Customizing the theme
      The module framework allows themes to be customized in order to provide flexibility, enhance the user experience, and maximize performance.
      - Theme Editor
        The Theme Editor portlet is a new addition to HCL Digital Experience Container Update CF193 and on-permises CF196 and later release capabilities. The portlet allows an administrator to edit static theme resources in WebDAV without the use of a WebDAV client or tool.
      - Editing static theme resources and connecting with WebDAV
        After you create a new theme, you can edit the static resources that are associated with the theme.
      - Copying your theme
        Starting with Combined Cumulative Fix 08, you can now copy your theme by using the Theme Manager. You can also choose to copy your theme manually.
      - Dynamic content spots
        The static template files use dynamic content spots to reference JSP files or other dynamic resources. The dynamic resources are stored in a WAR file.
      - Layouts
        You can apply ready-use layouts to your portal pages, modify the existing layouts, or add your own custom layout to change how your pages display.
      - Skins
        You can apply ready-use skins to your portal pages, modify the existing skins, or add your own custom skin to change how your pages display.
      - Menus
        You can customize the appearance and performance of your menus.
      - Theme templates (theme.html)
        You can use static HTML to write portal themes. The static theme template is named theme.html.
      - Changing the theme logo
        You can change the theme logo to customize your portal site and rebrand it to reflect your business.
      - Customizing navigation
        Use dynamic content spots to determine what is displayed by Top, Primary, and Secondary navigation. Use the navigation.jsp file to map properties to the dynamic content spot IDs in the theme.html files. Rendering of the navigation is done with a single JSP file with <ul> and <li> tags.
      - Styles
        HCL Portal 8.5 provides a selection of ready-use styles that you can be applied to your portal pages. You can also modify the existing theme styles or add your own custom style to achieve the look that you want.

There are several programming tools and techniques available for generating HCL Portal URLs in custom code. The following section introduces the programming tools available and discusses when it is most appropriate to use each of the tools.
  - Model SPI overview
    Models provide information that is needed by HCL Portal to perform tasks such as content aggregation or building navigation to browse the aggregated content. The information that is aggregated is represented through models that can be accessed programmatically by using the Model SPI (read-only). The information of a model is usually persistent (stored in a database) but can also be transient (computed and stored only in memory). Models can be represented by using a tree structure (nodes have a parent-child relationship), a list structure, or a selection structure (a selected element in a tree structure).
  - Controller SPI
    You can use the Controller SPI for portal administration. It allows you to modify portal resources. It enhances the read-only portal Model SPI by adding writable aspects.
  - User and group management
    The Portal User Management Architecture (PUMA) System programming interface (SPI) provides interfaces for accessing the profiles of a portal User or Group.
