If you would like to change the theme/skin you should go to Special:ManageWiki/extensions on your wiki, select the "skin" tab, and then check the boxe(s) for the skin(s) you would like to enable. If you want to change the skin for the whole wiki go to Special:ManageWiki/settings, select the "styling" tab, find the dropdown for the default skin and select your desired skin. If you want to change the skin for just yourself go to Special:Preferences -> Appearance and change it from there.
Thank you. But sorry, I really want to change the background like this one: https://browndust.miraheze.org/wiki/Brown_Dust_Wiki
Not like his of course, but change my background with my image. Can you help me?
In that case you would want to edit MediaWiki:Common.css and change the background-color object for the different objects. Take note that you must have the editinterface rights to do this. Let me know if you have any questions.
MediaWiki:Common.css is a page. I also see you have bureaucrat and administrator rights on that wiki so you should be able to edit it. As for how to do it this link may be of interest https://www.mediawiki.org/wiki/Customizing_MediaWiki_for_beginners. Let me know if there are anymore issues.
On the MediaWiki: Common.css page appears: / * CSS placed here will apply to all covers * /
So, on the page you sent me, as a configuration example, I can put the code in MediaWiki: Common.css, how to test that will work? At least that's what I understood now by logic. Is this page that does all the CSS settings of my mediawiki is this?
Dude, thank you so much for your attention!
Sorry. Understand. It really was incomprehensible. So rephrasing the question: How do I create a patch for images? What directory are they in? Because I do not have access to the server got it? So how do I point the image?
