Details

An associative array binding variable names to LESS code snippets representing their values.

Removed in v1.31 due to concerns about allowing unmaintainable cross-dependencies. Custom ResourceLoaderModule subclasses can override the getLessVars() method instead.

Adding an item here is equivalent to writing @variable: value; at the beginning of all your .less files, with all the consequences. In particular, string values must be escaped and quoted.

Changes to this configuration do NOT trigger cache invalidation.

Example

$wgResourceLoaderLESSVars = [
	'exampleFontSize' => '1em',
	'exampleBlue' => '#eee',
];

Default value

MediaWiki versions:

1.27 – 1.31

$wgResourceLoaderLESSVars = [
	/**
	 * Minimum available screen width at which a device can be considered a tablet
	 * The number is currently based on the device width of a Samsung Galaxy S5 mini and is low
	 * enough to cover iPad (768px). Number is prone to change with new information.
	 * @since 1.27
	 * @deprecated 1.31 Use mediawiki.ui/variables instead
	 */
	'deviceWidthTablet' => '720px',
];
