• You could create another css page by changing the content model of the page you wish to use to css, see https://www.mediawiki.org/wiki/Help:ChangeContentModel first change the content model and then create the page, for example your_css_page.css after you can use Extension:TemplateStyles like so <templatestyles src="your_css_page.css">
