There are different ways to import CSS, click on "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner.
If your CSS page has several lines of code that say @import, you may be able to combine them! By batch importing a collection of scripts with a single import, your CSS will load faster and look cleaner. Consider the examples below: on the left there is an example of several imports using the classic @import rule; on the right is how you can merge them in a single command, which will minify them increasing performance:
Classic imports Combined imports
@import url("/index.php?title=MediaWiki:LocalCSS1.css&action=raw&ctype=text/css");
@import url("/index.php?title=MediaWiki:LocalCSS2.css&action=raw&ctype=text/css");
@import url("");
@import url("/load.php?mode=articles&only=styles&articles=MediaWiki:LocalCSS1.css|MediaWiki:LocalCSS2.css|u:dev:MediaWiki:InterWikiCSS.css")

Note: CSS imports rules must be stated at the beginning off the page, before any other rule. Otherwise they won't work. Here's an example of the correct placement:

Wrong placement Correct placement
/** other styles **/
.example { 
/** imports **/
@import url("/load.php?mode=articles&only=styles&articles=MediaWiki:LocalCSS1.css|MediaWiki:LocalCSS2.css|u:dev:MediaWiki:InterWikiCSS.css");
/** imports **/
@import url("/load.php?mode=articles&only=styles&articles=MediaWiki:LocalCSS1.css|MediaWiki:LocalCSS2.css|u:dev:MediaWiki:InterWikiCSS.css");
/** other styles **/
.example {

Source Mode — The safe way to edit
Source mode is designed to handle complex html codes on an article, allowing to reduce the amount of unwanted code that is sometimes automatically added. Source mode is the best way to edit if you are using templates, or html tags such as <span>, <p>, and <div>. Click "Expand" to learn how to you can switch to this mode and make your code look cleaner.

Location Source

Here are some useful tips:

  • When copy or pasting content, always use source mode!
  • When you see Double Brackets Icon in the edit area of visual mode, it refers to a template, or content with code that is not supported or too complex for the visual editor to handle. In source mode you will see this content in full.
  • When you see Comment Icon in the edit area of visual mode, it refers to a comment. In source mode, you will see this content as <!-- -->.
  • MediaWiki has a special language called wikitext to make editing more easy. This language is supported in visual mode and will not break as easily as html.
  • Some html tags like <u> or <s> are supported in visual mode.
  • You can also enter source mode when creating or replying to threads in a forum, or when using a message wall by clicking Comment Source Modus underneath the edit area.
  • You can edit templates only in source mode.
  • Some html tags are not supported on the source mode such as <input>, <iframe>. These codes will only work on mediaWiki pages when using verbatim to import them on your page.


  • Since it's an css class the css will not work if:
  • You edit an article in the visual editor
  • You visit an article on an mobile platform or when the mobile skin is activated

In both situation the hidden content will be visible on default.

Other usefull css

  • Since the h-link class also support images as an hover. you can combine this css with HoverImageClass for the best results.
