It looks like you need to turn off the portlet headers and borders on the region where the banner is placed. For information on turning off region headers and borders, see Section 10.2.12, "Displaying or Hiding Portlet Headers and Borders".
If the style you are noticing applies to colored headers and borders, page portlets always take their header and border colors from the page on which they are placed. This is because the display of headers and borders is controlled on the target page, rather than from any values set for the source page's style.
One way around this is to edit the region in which the page portlet is placed and turn off the display of portlet headers and borders. If the page portlet contains its own portlets, you must also turn off the display of headers and borders for regions on the page portlet's source page.
For information on turning off region headers and borders, see Section 10.2.12, "Displaying or Hiding Portlet Headers and Borders".
Portlet background colors usually are specified by the style that is applied to the page on which the portlets are placed. With a page portlet, there is a way to display the source page's background color:
Edit the style that is applied to the page on which the page portlet is placed (the target page).
For the style element Portlet Body Color, remove the value from the Background Color field.
The background color specified for the page portlet's source page (that is, Background Color property of the Common style element) displays.
To illustrate this for yourself, create a page named Source and a page named Target. Create a Source Style for the Source page and a Target Style for the Target page. Set all the color values for Source Style to the red end of the color palette. Set all the color values for Target Style to the blue end of the color palette.
When you edit styles, a quick way to move from style element property to style element property is to click the style element property in the Preview section of the Edit Style page. This selects the style element property and displays all of its values for editing
Add some portlets and items to the Source and Target pages. Publish the Source page as a portlet. Place the Source page portlet onto the Target page.
For the Source page, experiment with selecting and de-selecting Use Style Of Page On Which Portlet Is Placed, and viewing the result on the Target page. Also, experiment with specifying and clearing the value field for the Background property of Target Style's Common style element.
For item types to appear on this list, they must be specifically included by the page group administrator who configures that page group. Ask your page group administrator to add the item type you are seeking to the page group's Available Item Types list. For more information, see Section 18.104.22.168, "Making an Item Type Available to a Page Group".
The page group has been configured to allow the addition of file-type items only. When a page group is configured to allow the addition of only one type of item, the Item Type Selection screen does not display when you click the Add Item icon. Instead, the Item Attributes screen displays, where you can start right in providing attribute values for the one allowed type of item.
Speak with your page group administrator. This is the person who determines the types of items that can be added to a page.
When a Smart Link item does not display, it can be due to one of a few reasons:
You do not have permission to use the functionality associated with the Smart Link. In this case, ask your page group or portal administrator to give you a higher privilege level on the link's target.
No value was entered for the page property associated with the Smart Link. In this case, if you have sufficient privilege, edit the page and provide a value for the related property.
The page group does not have the supporting configuration. For example, in the instance of a Subscribe Smart Link, the page group must be configured to allow for approvals and notifications.
Sub-page links regions have controls at the page and region levels.
At the page level, you can choose specific sub-pages to include or omit from display and you can select to display sub-page links alphabetically. These controls are on the Optional tab of page properties. For more information, see Section 7.9, "Defining the Display of Sub-Page Links".
At the region level, you can specify whether one or two levels of sub-pages display, provide a character to separate pages listed at the secondary sub-page level, select the attributes to display with each sub-page link, and choose the default or another icon that users click to navigate up the sub-page hierarchy. These controls are available when you edit a sub-page link region's properties. For more information, see Section 10.2.7, "Setting Sub-Page Links Region Properties".
If you have edit privileges on the page, you can edit the page, enter Layout view, and edit the defaults of the navigation page being used for the page banner. When you edit the navigation page's defaults, you can select specific regions for display. For example, you can de-select the region that displays sub-page links.
