It has to do with

/**

• @param $context ResourceLoaderContext
• @return array

	 */

public function getStyles( ResourceLoaderContext $context ) {

		$logo = $this->getConfig()->get( 'Logo' );
		$styles = parent::getStyles( $context );
		$styles['all'][] = '.mw-wiki-logo { background-image: ' .
			CSSMin::buildUrlValue( $logo ) .
			'; }';

		return $styles;

}

in file ResourceLoaderSkinModule.php. The file should use less and then add .background-image.svg( ) and in $logo in localsettings.ph do something like $logo = 'image.svg', 'image.png';

Or using http://www.quirksmode.org/css/condcom.html

Add support for svg with png fallback for logo

https://gerrit.wikimedia.org/r/193434

What's going on? Is there any negative review making it stuck? Or still waiting for any review?

@Dvorapa: See https://gerrit.wikimedia.org/r/#/c/193434/ (linked from T86229#1074657) and the code review comments there.

This https://gerrit.wikimedia.org/r/#/c/193434/ works, this will allow us to use svg images on Wikipedia whilst falling back to png on browsers that doint support svg :).

@Dvorapa hi, it is almost ready, need @Legoktm to take another look at the patch I just updated now and if he says it is ok, it can then be merged :)

Mostly for reference on gerrit...
