RSS is truly in its own little universe.

I recently became aware of RSS stylesheets. Apparently there is a specification for that called XSLT which is distinct from CSS in both form and function. However, there are plans by Google/Mozilla to remove XSLT from their browser engines for security/maintainability reasons. Apparently RSS supports javascript though, so it's possible to manipulate the RSS DOM that way. One could imagine a javascript polyfill that interprets XSLT, although I'm not sure if there's some cross-site security issues that would make that impractical.

More like a little island in the XML archipelago.

XSLT is a bit more than just “RSS stylesheets”.

The removal was discussed here: https://news.ycombinator.com/item?id=45873434

No need to imagine a polyfil, they already exist: https://github.com/mfreed7/xslt_polyfill

If you want to style RSS, you can just go straight to JavaScript and avoid all the XSLT mishegas.

I made a site with to get people started: https://www.rss.style/

Example RSS feed: https://www.rss.style/changelog.xml

Cross-site is fine by default, though the script is small enough to easily self-host. If you have a content-security-policy, you'll need to allow the host in script-src.
