The Oracle Alta UI skin is meant for new development and is an opt-in. To use Oracle Alta UI skin instead of Skyros, there are a few configuration steps. You configure your application to use the new skin by specifying values for the <skin-family> and <skin-version> elements in your application's trinidad-config.xml file, as shown below.

To apply an ADF skin to an application

1. In the Applications window, double-click the trinidad-config.xml file. By default, this file is in the Web Content/WEB-INF node.
2. In the source editor, write entries to specify the value of the <skin-family> element and, optionally, the <skin-version> element as shown in the example below.

<?xml version="1.0" encoding="windows-1252"?>

<trinidad-config xmlns="http://myfaces.apache.org/trinidad/config">

    <skin-family>skyros</skin-family>

      <skin-version>v1</skin-version>

</trinidad-config>

The values that you specify for the <skin-family> element and, optionally, the <skin-version> element in the trinidad-config.xml file determine the ADF skin that the Fusion web application uses at runtime.
