Every language has automatic formatters. Use them, configure them if you don't like the default (in accordance with your team), and configure your editor so that is applied automatically when you save. And use CI to detect PRs with bad formatting so devs who don't have configured their editor yet can't break it.

Same with linters, you still have to agree with your co-workers about which rules make sense to be enforced, but with good editor integration you can see it right away and fix it as you code.
