Help:Templates
This article is all about using templates on Nookipedia. It will teach you how to add and use templates in articles.
What is a template?
A template is a CSS/HTML code which has been saved in a manner so that you don't have to type it out every time you want to add it to an article. Take the Help Navigation Box. It is a custom modified navigation box template. Although the natural template has a red color, the help box has been changed to blue. Some templates also add articles to categories so you don't need to write the code for that. Adding and Using Templates
Most site/high traffic related templates are protected for admin editing so that they don't get vandalised, but all userboxes are not protected so anyone can add them to their profile. To add a template you can just add {{ and }} around a template name such as the roundy template. The template will automatically show up (to the latest incarnation of it anyway) to the users.
Userboxes?
Userboxes are boxes that have been made by modifying the userbox template. You can create your own and add it to your profile and then to category for others to do the same.
