If you need them in the HTML and they are really important, you can use addModuleStyles instead. However use it sparingly as using that makes it harder to cache things properly, produces slightly more http request overhead. The client side loader allows all kinds of useful cache features, load optimisations, dependency resolution and rapid global cache puring without requiring a purge of every single page of the wiki. This is what enables Wikipedia to deploy new code in ~ 5 minutes globally without invalidating anything in the HTML. Historically speaking relying on javascript to load styles may seem odd, but nowadays it is worth it and is in many cases even faster due to being non-blocking (where appropriate). Loading with javascript also doesn't mean that it will flicker. That only happens if the module is loaded from the bottom. Set 'position' => 'top' in your module and load with addModules() to load it from the top. That should fix the flash of unstyled content. -- Krinkle [1] http://www.mediawiki.org/wiki/Manual:$wgResourceModules [2] http://www.mediawiki.org/wiki/ResourceLoader/Features _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
