Returns:
-
String
The class attribute and value, if the item is the first or last item in the collection, or an empty string otherwise.
A useful method to add ‘class=”first”‘ or ‘class=”last”‘ (or other classes as specified in $args) to HTML tags as you loop through the collection, without needing to track this yourself. Using this requires a fairly specific loop code-pattern, specifically the index needs to be exposed in the foreach loop with the => syntax – please see the example.
Parameters:
-
The index of the item in the list, which mast be passed from a loop variable that tracks it (see example).
-
An arguments array or string with the following params:
* first: the class to apply to the first item – default “first”
* last: the class to apply to the last item – default “last”
