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

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
