When you delete a style, all pages and item regions that used the style revert to the page group default style. If the page group default style is <None>, all pages and regions revert to the system default style.
You cannot delete the system default style, nor can you delete the style created automatically when a page group is created.
To delete a style, you must either have created the style or have at least the page group privilege Manage Styles on the page group that owns the style.
To delete a style:
Log in to Oracle Portal.
Click the Build tab to bring it forward.
From the Page Groups portlet Work In drop-down list, select the page group that owns the style to be deleted.
By default, the Page Groups portlet is located on the Build tab of the Portal Builder page.
If the style is used by more than one page group, it will be in the Shared Objects page group.
In the Layout & Appearance section, click the Browse link next to the Styles heading.
The Portal Navigator opens, displaying a list of the selected page group's styles.
Click the Delete link next to the style to be deleted.
In the confirmation page, click Yes.
Optionally, click the Builder link at the top of the page to return to the Page Groups portlet.
