Method: Sass::Script::Functions#join

Defined in:
lib/sass/script/functions.rb

#join($list1, $list2, $separator: auto) ⇒ List

Joins together two lists into one.

Unless $separator is passed, if one list is comma-separated and one is space-separated, the first parameter's separator is used for the resulting list. If both lists have fewer than two items, spaces are used for the resulting list.

Examples:

join(10px 20px, 30px 40px) => 10px 20px 30px 40px
join((blue, red), (#abc, #def)) => blue, red, #abc, #def
join(10px, 20px) => 10px 20px
join(10px, 20px, comma) => 10px, 20px
join((blue, red), (#abc, #def), space) => blue red #abc #def

Parameters:

  • The list separator to use. If this is comma or space, that separator will be used. If this is auto (the default), the separator is determined as explained above.
