Hey HN,<p>Tailor is a developer tool that aims to simplify inspecting spacings, distances between elements, and fonts on websites.<p>Our QA does a lot of checks to ensure that spacings, paddings, and font sizes match the designs. So I thought there should be an easier way. Honestly, I would expect something like this to be built inside the browser inspector.<p>It is available as a browser extension (Firefox and Chrome) and as a library. You can load it as a bookmarklet too, but I found the extension more convenient. You can try it live on its homepage.<p>I want to add a way to take screenshots while the overlay is visible (useful when reporting an issue) and a few minor tweaks. It is open-source and written in TypeScript. For issues and feature requests, please use GitHub:<p><a href="https://github.com/Stanko/tailor/">https://github.com/Stanko/tailor/</a><p>It doesn’t track anything nor uses any user data, and it is going to stay that way.<p>Let me know what you think, thanks!
