Help:Syntax highlighting

Syntax highlighting is a feature designed to improve readability of code on FANDOM. It takes what is written in the editor and highlights the various types of code in different colours to help a reader identify which parts do what.

It exists in three main forms - simple wikitext highlighting, CSS/JS/template/Lua page highlighting, and as a tag usable on articles.

Simple wikitext highlighting
Wikitext is the main building block of articles across FANDOM, but it can often be hard to comprehend what you're seeing at a glance, especially on more complex pages.

 * olive = templates and HTML versions of special characters
 * blue-violet = section headings, horizontal lines, bold and italic text
 * light blue = internal links
 * pale blue = external links
 * red = general wikitext
 * red-violet = tags
 * grey/brown = templates and HTML versions of special characters

Code highlighting
CSS, JS, infobox template, and Lua module pages have a more advanced syntax highlighter active.

If you do not wish to use syntax highlighting, simply visit the 'Editing' tab in your preferences, and tick the "Do not show syntax highlighting in Source mode" option.

This will switch off all forms of syntax highlighting, including on CSS and JS pages.

Article highlighting
