Module:Portal bar

This module implements the साँचा:tl template. It displays a horizontal bar of portals.

See साँचा:tl 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 साँचा:para is equal to no, n, false, or 0, then the portal box will have no border.
• redlinks - if साँचा:para is equal to yes, y, true or include, then the portal box will show redlinked portals

Examples

• {{#invoke:portal bar|main|Art|Science|Literature}}

Produces:

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