== Overview ==
The {{tl|CSS}} template is a helper utility used to load [https://www.mediawiki.org/wiki/Help:TemplateStyles TemplateStyles] (CSS) from a specific subpage. 

Unlike a direct {{#tag:templatestyles}} call, this template uses the [[mw:Extension:Variables|Variables extension]] to **deduplicate** style tags. If the same stylesheet is requested multiple times on a single page, it will only be output once, preventing the accumulation of redundant `<link rel="mw-deduplicated-inline-style">` tags in the HTML source.

== Usage ==
Insert this template at the top of a template or module page to load its associated `/styles.css` subpage.

{{tl|CSS|PageName|NamespaceID}}

* **1** (Optional): The base page name. Defaults to the current page name.
* **2** (Optional): The Namespace ID. Defaults to 10 (Template).
** 0: Main/Root
** 4: Project (Starsand Island Wiki)
** 10: Template
** 828: Module

== Technical Details ==
* **Deduplication Logic**: It defines a variable `ts_loaded_[path]` the first time a style is loaded. Subsequent calls to the same path are ignored.
* **Dependency**: Requires the [https://www.mediawiki.org/wiki/Extension:Variables Variables] extension to be installed on the Wiki.

== Examples ==
=== Basic Usage ===
To load styles from the current template's `/styles.css` subpage:
* {{tl|CSS}}

=== Specific Page ===
To load styles from a specific template:
* {{tl|CSS|Infobox Item}}

=== Specific Namespace ===
To load styles for a module:
* {{tl|CSS|Common|828}} (Loads `Module:Common/styles.css`)
