The category contains formatting and function templates. Templates in this category will likely have a description on the templates project page. If not, they probably deserve one.

Using this category

To put a template in Category:Formatting and function templates:

• Use <includeonly>[[Category:Formatting and function templates]]</includeonly> on the documentation page (see Template:Documentation for more info). Ensure that the {{Documentation}} is surrounded by <noinclude> tags on the main template page, and that the category on the documentation subpage is surrounded by <includeonly> tags to ensure that the template and only the template is categorized into in the template category!
• If your template is meant to be used in-line, try and make sure that there are as few line feeds (breaks, whitespace, etc.) as possible.
• Remember that a template can be put in multiple categories if it belongs to them all!
• Or, if this is not quite the right category, go back to Category:Templates and try to find a better suited subcategory.
