Help:Cascading Style Sheets

Cascading Style Sheets allows for flexible formatting of a page. They should be used instead of tables for non-tabular content whenever possible, because they can be manipulated by the reader or overridden by an author if your CSS is embedded in another page via a template.
Style depending on a parameter or variable
Variable class or id
A class or id can depend on the result produced by a template or on a template parameter, e.g. class="abc{{{1|def}}}". For one or more of the possible class names the style of that class can be defined. If the class is undefined it is ignored, so the standard style is used.
In the simplest case we have e.g. class="abc{{{1}}}" and define class abcdef. If the parameter value is "def" it applies.
If a page for general use only makes sense when styles are defined for certain classes, then these have to be specified in the page MediaWiki:Common.css, which applies for all users and all skins, as far as not overridden.
Variable style parameter value
Wikitext that reads
<span style="display:{{{3|none}}}">Wed</span>
will display "Wed" if parameter 3 is defined, but its value is not "none", and displays nothing if parameter 3 is undefined or "none". If the value of parameter 3 is a display style other than "none", that style is applied.
Wiki headings
Wiki headings use the following default CSS:
| Wikimarkup | HTML | Style |
