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…

What it does

In the maker’s words, at launch

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 switching via attributes on <html>, custom styles and theming are now manageable using it. There are a few examples in the friendly release notes above, with screenshots and copy-pasteable CSS. If you just want to grab the stylesheet which sets up the CSS variables and application rules to use in your own thing, it's here [1], but not _everything_ is themeable without a bit more work - in particular, I had to replace the HN <img src="y18.svg"> logo with an inline version of the SVG, so its fills can be controlled by CSS.

    Hi HN, I've designed the site based on what I wanted a couple of years ago when I had been looking for a remote job. It's very early and any feedback is appreciated. I've also used this opportunity to reduce some of that front-end framework fatigue by using just HTML, CSS, and JavaScript. Edit: I'll add location and salary filters as soon as I wake up tomorrow

    I made a modern web UI for Hacker News2022 · modernhn.com · ▲308

    Hey HN, I made this free browser extension that modernizes the Hacker News design. I previously launched Modern for Wikipedia [1] here back in December, and it seemed like the obvious next choice to build one for HN too! So I've taken what I learned from building that, and have spent all my spare time this year building Modern for HN. I realize this won't be for everyone, but it was a fun project to work on, and I'm really happy with the result so far. Hope you like it too! Lots more planned for future updates, and suggestions welcome :) [1]…

    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:&#x2F;&#x2F;text.blogosphere.app&#x2F; Non-minimal: https:&#x2F;&#x2F;blogosphere.app&#x2F; If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
