On Wikipedia, HTML <span>...</span> elements are used to group logically related text. They allow:
- Explicitly setting the CSS style for an inline run of text
- Explicitly setting the language for a run of text (for cases where the rendering differs from language to language; this is generally done through the
{{Lang}}templates, not with manual span markup) - Explicitly setting the direction of the text (LTR or RTL).
- Avoidance of other HTML tags, such as
<s>and the now-deprecated<strike>, which would otherwise be used as workarounds, but are less suitable. - Syntax highlighting; code excerpts can be colorized for easier reading, customizable with CSS.
- Various uses in infoboxes and navigational templates.
- Specification of class and id attributes for certain boilerplate messages which should be inlined; e.g., {{merge}}.
- Citation templates (see above).
- Setting anchors in the text to which incoming links may jump; this is usually done with the
{{Anchor}}template.
Almost all HTML tags that are allowed in Wikipedia permit inline CSS styles.
