You can make a style that you create available for other users to apply to their own pages.
To
make a style available to other users, you must have at least one of
the following privileges:
Manage All privileges on the page group to which the style belongs
Publish global privileges on All Styles
In the Navigator click Edit next to the style with which you want to work.
Tip: If the style is used by more than one page group, it will be under the Shared Objects page group.
Tip: If you do not know the name of the style you want to change, edit a page or region that uses the style. When editing a page or region, you can also edit the style used by that page or region.
