Editing Wiki (section)

==== Source editing ====

Some wikis will present users with an edit button or link directly on the page being viewed. This will open an [[user interface|interface]] for writing, formatting, and structuring page content. The interface may be a source editor, which is text-based and employs a lightweight markup language (also known as ''wikitext'', ''wiki markup'', or ''wikicode''), or a [[#Visual editing|visual editor]]. For example, in a source editor, starting lines of text with [[asterisk]]s could create a [[Bullet (typography)|bulleted list]].

The [[syntax (programming languages)|syntax]] and features of wiki markup languages for denoting style and structure can vary greatly among [[List of wiki software|implementations]]. Some allow the use of {{abbrlink|HTML|Hypertext Markup Language}} and {{abbrlink|CSS|Cascading Style Sheets}},<ref>{{Cite book |last1=Dohrn |first1=Hannes |last2=Riehle |first2=Dirk |chapter=Design and implementation of the Sweble Wikitext parser: Unlocking the structured data of Wikipedia |date=2011 |title=Proceedings of the 7th International Symposium on Wikis and Open Collaboration |chapter-url=https://dl.acm.org/doi/10.1145/2038558.2038571 |language=en |publisher=ACM |pages=72–81 |doi=10.1145/2038558.2038571 |isbn=978-1-4503-0909-7}}</ref> while others prevent the use of these to foster uniformity in appearance.
