Pre-formatted text

There are a number of ways to include pre-formatted text (e.g. source code fragments); all of these techniques also use a fixed-width font for the text:

  • Start each line with a space character; normal markups can be used; e.g.:

" This is '''pre-formatted''' text"

produces:

This is pre-formatted text
  • Use the HTML <nowiki> tag, with a space character before the <nowiki>. (Remember to add a matching closing tag after the pre-formatted text block).
  • Use the HTML <pre> tag (again, remember the closing tag).

Note that the HTML <blockquote> tag only indents the block; text within it will still be justified.

Tables

{| class="wikitable"
! Table !! Prototype
|-
| colspan="2" style="text-align:center;" | Headers
|-
| aa || rowspan="2" | yy
|-
| bb
|-
| cc || zz
|}

produces:

Table Prototype
Headers
aa yy
bb
cc zz

Images

[[Image:Pdp1115.jpg|thumb|150px|left|Caption text]]

produces:

Caption text

Leaving out the '150px' inserts the image full-size. The optional keywords 'left' and 'right' can be added to control the horizontal placement.

New images can be uploaded via the 'Upload file' page (link on the left-hand side of all pages).
