I have a website with multiple languages. How exactly do I set the language tag to match the respective content on each individual page?
You mean you have EN IT DE BR tags in your navbar, which is the same (symbol) for all page, and you want to be able to switch from site.webflow.io/en/thispage to site.webflow.io/br/thispage automatically?
This would required extra code, like Javascript. We do it on a site with an extra program on the server that intercept any click on the tags, check the page you’re on and write the appropriate URL automatically. I didn’t dev that so that’s all I know about.
