11.13 Troubleshooting Styles

When I create a page, I am not given the option to select a style for the page.

If the page is based on a Portal Template that does not allow privileged users to choose their own page style, the style selection screen does not display when you create a page, and the Style tab does not display when you edit a page. If you have sufficient access to the template, you can edit the template and select Enable Pages To Use Different Style on the Style tab of template properties. Once this setting is selected, the Style tab displays in page properties.

Another possibility is that the page group that owns the page is not configured to allow privileged users to manage a page style. This option is available on the Main tab of page group properties. It must be selected for users to select a style for any pages in the page group.

How do I control the appearance of hyperlinks in, for example, text items?

The Plain and <None> selections provide the same effect for most item types. However, when applied to items displayed as hyperlinks, they behave differently:

When I logged in today, all the colors and fonts were changed on my page.

If the page is based on a template, it probably uses the template's style selection. Whenever a template's style selection is changed, all the styles on all the pages that are based on the template also change.

This is true unless the template allows pages based on it to use their own style. In such cases, changes to the template style selection do not affect pages that are based on the template.

I cannot apply styles to my regions; the Styles tab does not display on the Edit Region page.

Is the region a portlet region? Portlet regions cannot have their own style.

It might also be privilege-related. It is not enough to have the page privilege Manage, the page group option Allow Privileged Users to Manage Styles must also be selected for you to be able to change region styles. Ask your page group or portal administrator either to select this option for the page group, or to grant you a higher level of privilege, for example, the page group privilege Manage Styles.

My page portlet is using the style of the target page rather than the style of its source page, as I have specified.

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 at the region level, 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, and click Apply. 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.

Tip:

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.

My page portlet is not using the style of the container page, as I specified.

When you publish a page as a portlet, you are given the opportunity to use the source page's style or to use the style of the containing page. Using the style of the containing page works in most cases. The exception is when the source page is provided through the Federated Portal Adapter. In such cases, the setting to use the style of the containing page is ignored. The page portlet uses whatever style is applied to its source.

My style specifies a page background color, but no color displays.

When a page uses an HTML page skin template, the page background color is taken from the template and any background color specified in a defined style is ignored.

An exception to this is when the page skin uses a class generated by an Oracle Portal style. For example, you can place an Oracle Portal style element class in the <body> HTML tag: <BODY style="margin:0px" class="Bodyid2siteid0">. Should you change the style declaratively, through the Oracle Portal user interface, the change is reflected as well in the template that references the style class.

This enables you to change the Background Color of all pages that use the page skin through the declarative style. (For more information on Oracle Portal style element classes, see Section 11.12, "Using Portal Style Element Classes in HTML Templates and CSSs".)

My portlet/tab corners are not rounded.

Check the applied style's Common style element, specifically check the hexadecimal value entered for the Background property's Background Color attribute. If you enter a hexidecimal color value that does not also appear in the color palette, tabs and portlets do not display with rounded corners.

I have applied my own CSS to my pages through an HTML template, and my results are very uneven.

It could be that the HTML template not only calls the CSS but also includes the #page.style# HTML template substitution tag. Or the template header includes Oracle Portal style element classes between <style></style> tags as well as the #page.style# tag.

If either of these is the case, consider removing the #page.style# tag. This tag calls the Oracle Portal style, which may include the same style element classes specified in the CSS or embedded between the <style></style> tags. This causes conflict, with the portal doing its best to figure out which style element class specifications to use.

It might also be that you have not applied the Main style to all relevant pages. If so, then the variable values associated with some of the style element classes (idnsiteidnn) do not match up with those of the Oracle Portal style selected for the page.

Go to all affected pages, and select the Main style. The Main style, which comes from the Shared Objects page group, always provides the variable values id1siteid0, making it predictable and thus allowing for consistent results.

My Page portlet/navigation page is using the background color of the container page, rather than the source page, as I prefer.

To ensure that a page portlet or navigation page uses its own background color, rather than the one specified for the page it is placed on:

  1. Ensure that the page portlet or navigation page uses its own style when it is published as a portlet (that is, do not select this option for the page or navigation page that you are using as a portlet).

  2. In the style that is used by the target page (that is, the page where you place the page portlet or navigation page), set Portlet Body Color style element to Null (no value).
