Control the look and feel of the site by changing the theme
or skin. A theme controls elements of the overall portal, such as
the banner and navigation. A skin controls portlet elements, such
as the minimize and maximize icons and the title bar.
Note: For WebSphere Portal Version 7 and later
versions you need theme management rights to be able to create, update,
and delete themes and skins. For details refer to the portal information
center topics about access
rights.
