Themeable HN
Hi HN, I needed a distraction from the new and scary thing I was working on this weekend, so I grabbed HN's stylesheet, extracted CSS variables for every colour it defined, then re-applied them back onto HN using its own selectors (plus some extras for bits of HN which are styled inline, and some separation between header and content styling), allowing it to be themed with variables. After using them to implement a dark mode (and a pure black variant for OLED), plugging everything into my existing HN browser extension which already lets you apply custom CSS, and making it handle theme…

Winamp and other media players, rebuilt for the web with Web Components2024 · player.style · ▲392Hey all, creator of Video.js and co-founder of Mux & Zencoder here. My team and I built this. I hope you like the themes we’ve built so far, and maybe even get inspired to build your own. I know Web Components are in a bit of a drama cycle right now. I’m happy to see them get any attention really. I’ve been pretty bullish on them since ~2013 when I started working with them, at least in the context of a widget like a video player.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
