Help:Infoboxes/CSS

Portable infoboxes can be themed quite easily by local admins using a wikia's community CSS.

Without customizations, portable infobox theming takes cues from your community's Theme Designer settings, particularly the article background color and link color.

Infobox themes
The default infobox theming can be overridden using local community CSS, and using the theme or theme-source attributes on the infobox tag will make it easy to target specific infobox templates using classes.


 * The theme attribute is used to specify a custom CSS class for the infobox template.
 * The theme-source attribute allows you to vary the CSS class via a template parameter.

Using "theme"
For example, theme="delta" will add a class called pi-theme-delta to the infobox HTML, which can then be customized using CSS:

As an example, the code below could then be used to change the secondary background color to red:

Using "theme-source"
For example, theme-source="location" means that, when location is specified in an article's infobox, it will use the value of it as the class.

For example:

If you want to target specific elements within that particular infobox, you would do then something like this:

Advanced theme notes

 * If both theme and theme-source are used, the theme attribute is treated as the default (for when theme-source is not defined).
 * Spaces in the values of theme and theme-source are converted to hyphens, meaning only a single class can be added.
 * If no theme is specified, .pi-theme-wikia will be used instead.

Advanced
Normally, if you need to change the styling for a specific theme you would write something like this:

However, when a CSS class is on the same element as another and you need to select for both, leave no space between the classes. For example,  is on the same   element as the theme  and general portable infobox class, so CSS that changes the background for that theme would be:
