24 alternatives to Nest Your CSS

Hey HN, About a year ago, I found out about native CSS Nesting but was surprised to find no simple, pure CSS converters online. The closest were CSS-to-SCSS tools that often produced invalid (pure CSS) code that required manual refactoring. So, I decided to build my own. It started as a barebones MVP (quickly.nestyourcss.com), but I got carried away with a personal challenge: could I turn a simple A-to-B online converter tool into something that felt like an "Awwwards-level" website? I'm not a designer, and I know I didn't fully hit that mark, but it was a fantastic learning experience and…

   Convert any website into a React component▲326

   Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component. Demo video: https://youtu.be/hutUYDkyE_A How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out…

   http://instacss.com (in case DNS update hasn't propagated: http://morning-warrior-3377.herokuapp.com/) Last night I was annoyed at how slow (and web 1.0-ish) most CSS reference sites seem to be, so I created this. It's basically a scrape of the CSS reference on w3schools, but with client side searching. Feedback is most welcome! some of the tech involved: node, requirejs, backbone, mongodb the code: http://github.com/rgarcia/instacss

    Selector Forge▲133

    Hi HN, I'm Ahmad from the Intuned (https://intunedhq.com) team. Today, we're releasing and open-sourcing Selector Forge (https://selectorforge.ai/), a browser extension that generates reliable CSS/XPath selectors using AI. You can use it to create a selector for a single element or for an array of elements. The selectors it creates are meant to be "semantic" and more resilient to page changes than what Chrome DevTool’s “Copy Selector” (and other similar extensions) give you. Those tend to hand you something brittle like `#top > div.w-100.ph0-l.ph3.ph4-m > h1 >…

    Browser-based web design platform with code import and CSS filters▲91

    I built a web-based app for building websites. The main unique features are: 1. The ability to copy and paste any HTML and CSS into the editor with no limits. I was never able to find another app that could do this without some form of limitation. 2. CSS filtering, which means you can click on an element to view and edit the CSS selectors and rules that apply to that element alone. In many cases I've found CSS naming conventions like BEM to become irritating at certain scales, so this is an alternative solution. This part of the app needs some more development work but the concept is there.…

    A list of CSS authoring rules with examples and a Stylelint config accessible from the top of the page. I've come to these through 20 years of experience and a willingness to make vanilla CSS a better alternative to frameworks. I encourage you all to comment on the rules themselves and the Stylelint Config for ECSS. Here's the link for faster access (I still suggest at least zipping through the rules beforehand). https://www.npmjs.com/package/@efficientcss/stylelint-config...

    Hi HN, founders of VibeFlow (YC S25) here. We mostly work on backend and workflow tooling, but we needed a way to turn Figma designs into frontend code as a kickstart for prototyping. It takes a Figma frame and converts it into React + Tailwind components (plus assets). If you want to try it: You can run it locally or use it via the VibeFlow UI to poke at it without setup (https://app.vibeflow.ai/)
