There's `position: sticky` now for headers. It has better ergonomics than fixed and it's nice than it's supported by all modern browsers.

It's a huge improvement for sticky sidebars that are only scroll within their parent element. For example, it's what I use on this page: https://allaboutberlin.com/guides/public-transit
