In my opinion, that’s a bigger problem than CORS. Proxyless web feed reader is a lost cause, you’re wasting your time because only a small minority are ever going to support it. But that opacity and transition nonsense gratuitously slows down page loading for everyone, and hides content completely for those that aren’t running JS.
(What I would also like to know is: how come this is the third time I’ve seen exactly this—each block of content having this exact style attribute—in the past month, when I don’t remember encountering exactly it before?)
And to answer your question, you're seeing that kind of styling so frequently because it's likely part of Framer Motion, an extremely popular animation library
https://www.npmjs.com/package/framer-motion https://www.npmjs.com/package/motion
Is the fade effect really worth having parts of your site disappear at random?
So, basically, any URI that I need to resolve goes tries first to fetch directly and it falls back to making the request through the proxy if I get any type of authentication error.
If CORS weren't an issue, it could've been done in 1/10th of that time. But if that were the case, there would've already been tons of web-based RSS readers available.
Anyway, the goal of this project is to help foster interest in indie blogs and help a bit with discovery. Feel free to submit your blog if you'd like!
If anyone has any questions, I'd be happy to answer them.
