This template trims whitespace from a string. The string should be passed as the first unnamed parameter. One may substitute this template - that is, if used as {{subst:trim}}, the resulting wikicode is "clean".
Usage
{{trim|text}} = text with any leading or trailing whitespace removed.
Example
- {{trim| abc}} produces abc.
