233:, a proposal was made to use a meta-template. In this area, it is much better to decide on a common look and format, document that standard for easy reference in case new related templates are needed, and then implement it across the few templates being used. When changes are needed, this gives one central place for discussion and revision. After there is consensus for the change, interested editors can quickly apply them. Creating a page which displays each template also helps to locate templates which don't follow the agreed upon format.

classes could be added to the site's global stylesheets. The meta-templates could then be replaced with the CSS classes in relevant pages. This would accomplish the same purpose — maintaining uniform style across the site — without placing a burden on the server. This also allows the visual style to

While they can be extremely useful and convenient, it is proposed that they be avoided due to concerns that may not be immediately obvious: Meta-template schemes can be fragile and hard for new editors to understand. They may also provide an avenue for mass-vandalism and impact maintenance efforts.
119:
Nested template schemes are complex and prohibitively difficult for the average editor to grasp. This is particularly true in non-technical areas where the subject expert, who knows best what information should be presented in a template, is not able to edit the template due to the use of esoteric

Thus, caution is warranted for those nested templates which are widely used indirectly. A sub-sub-sub-template could be vandalised with offensive content. These could be difficult to notice immediately, because the sub-template is not edited often and appears on only one or a few

Template links created by meta-templates also frequently cause problems for template namespace maintenance. If a
Template:A is in use on several pages, but then is changed to either add or remove Template:B, any article-level template links to "B" are not updated until each article is edited or

When a page is edited, a list of all templates in use on that page is stored in the database. This list can be seen when in edit mode as a list of links at the bottom. Not only are the templates that are directly called listed there, but any higher-level meta-templates as well. This feature was

It should remembered, however, that it is possible and useful to write a meta-template which will only be used on a few or even a few hundred pages. Conversely, there are templates, such as cross-reference templates, which are very widely used without being meta-templates.

You should not use meta-templates without good reason. If you do create one, be open to other methods which achieve the same end, and be prepared to trade functionality in favor of avoiding the problems with meta-templates.
