The previous formatting of the wiki used templates very sparingly. One of my goals is to make the use of templates much more widespread and systematic. This will make maintenance and formatting easier long-term.
The main focus there has been on the Recipes page. Every item in a cooker recipe is now presented using individual templates for each item, basically {{Item Name Minicard}}. All the information (except amount of items crafted) is then part of the template.
Each of those item minicards then call the same Minicard template, making the formatting very regular and separating formatting from data content.
