There is one important reason why we use <link> instead of <style>…</style>: when the rendered page HTML is cached, e.g. using a caching proxy like Varnish [1] or MediaWiki file cache [2], then if we used <style>…</style>, you would have to purge every page on the wiki before changes to MediaWiki:Common.css would actually take effect, because the CSS would be embedded in the cached HTML. Using <link> means that it only takes as long as it takes the cached resource to expire in the users' browsers. (By default, they are set to expire after 5 minutes.) If you don't have caching enabled, then of course that wouldn't matter – but also, if you don't have caching enabled, then that is probably a much worse performance problem than not embedding the styles :) [1] https://www.mediawiki.org/wiki/Manual:Varnish_caching [2] https://www.mediawiki.org/wiki/Manual:File_cache -- Bartosz Dziewoński _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Also, I should note that I tested with MW 1.32 alpha (Git master). I don't know if older versions behave differently. -- Bartosz Dziewoński _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
