Wiki markup
From WWR
Wiki markup is the language, or syntax, used to control how things look and where they are placed on wiki pages. Some tags determine what happens when a user clicks a link or button.
Similar to other markup languages like HTML, wiki markup is the addition of punctuation and words to the text of a page in order to format the text, define the page layout and display images. The additional punctuation and words are often called "wiki tags".
Like other text tagging languages, wiki markup uses the concept of opening and closing tags to apply the formatting to the text or element between the opening and closing tag. For example to make a section header in wiki markup, you enclose the header in a balanced number of equal signs. (i.e., == This is a header ==) The first set of equal signs tells the wiki parser, "I want to start a header here," and then formats the header in a larger or bold font, sometimes with an underline. The second set of equal signs tells the parser, "OK. That's the end of the header. I want to write normal text now."
Example:
| What you type | What you see |
| == New section == | New section
|
Tags must be balanced in order for the elements to display properly. The example of header tagging above with the same number of equal signs on each side of the header is one type of tag balancing — that of having an equal number of the special syntax characters on each side of the text to which the formatting is applied. Wiki markup also uses this type of balancing for making text bold and italic.
Another type of balancing is specific opening and ending tags. The opening tag looks something like this, <s>, the text to be formatted or the name of the element is written next. Then a closing tag finishes the formatting. The closing tag of the tag pair is same as opening tag, but with a forward slash (/) between the first pointy bracket and the tag name. Like this, </s>.
Example:
| What you type on pages | What you see |
| <s>strike me out</s> | |

HTML and CSS markup can also be used in wiki pages.
