This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This Lua module is used on approximately 161,000 pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
This module depends on the following other modules: |
This module uses TemplateStyles: |
This module implements the {{portal bar}} template. It displays a horizontal bar of portals.
See here and here for testcases.
Note: in order to make the test cases work, the Sandbox CSS classes have "-sand" appended to their names. If you wish to update the CSS, copy the contents of each class from Module:Portal bar/sandbox/styles.css to Module:Portal bar/styles.css, but do not alter the class names, nor just copy-paste the entire CSS file. For the current difference in CSS between Sandbox and Main, see here.
Usage
{{#invoke:Portal bar|main|''portal 1''|''portal 2 ''|...|border=''no''}}
- Positional parameters - the names of the portals to be displayed.
border
- if|border=
is equal tono
,n
,false
, or0
, then the portal box will have no border.redlinks
- if|redlinks=
is equal toyes
,y
,true
orinclude
, then the portal box will show redlinked portals
Examples
{{#invoke:portal bar|main|Visual arts|Science|Literature}}
Produces:
{{#invoke:portal bar|main|Visual arts|Science|Literature|border=no}}
