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.

{{#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 to no, n, false, or 0, then the portal box will have no border.
  • redlinks - if |redlinks= is equal to yes, y, true or include, then the portal box will show redlinked portals
  • {{#invoke:portal bar|main|Visual arts|Science|Literature}}

Produces:

  • {{#invoke:portal bar|main|Visual arts|Science|Literature|border=no}}

This module uses Module:Portal to get portal images. To add, change, or remove images, please see the instructions at Module:Portal#Image.
