A Chrome extension that extracts used CSS and combines it into one file
just wanted to share this useful tool with you. I have been looking at something like this for a very long time. https://chrome.google.com/webstore/detail/css-used/cdopjfddj... what it does: it analyses your html dom and looks for css classes. Then it extracts it all and combines it into 1 single css file. I used 5 css framworks which was on 340kb kb. This tool made it 36kb!

In plain words
This Chrome extension analyzes a website's HTML structure to identify which CSS classes are actually used, then extracts and combines them into a single optimized file. Designed for web developers and designers, it removes unused CSS bloat from multiple frameworks. The tool significantly reduces file size—for example, consolidating 340KB across five CSS frameworks down to 36KB.

Chrome extension that extracts HTML+CSS from an element to inline style2022 · chrome.google.com · ▲7Hi there. I spent the last couple months building this chrome extension to scratch my own itch. It allows you to extract a snippet of HTML along with its styles and export to inline styles or JSX. It’s not perfect and doesn’t work on every site. There is class support but I am still working on it along with some other cool features. Feedback is appreciated.

Retool▲640Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
