Amino

Amino is a browser extension that puts a live CSS editor directly into your browser. It lets you change the appearance of any website you visit. You can adjust colors, fonts, layouts, and more by writing or pasting CSS code. The changes happen in real-time, so you see the results immediately as you type. This makes it a practical tool for experimenting with designs or creating a personalized version of a site you use often.

The tool works as a compact sidebar or panel within Chrome. It doesn't require you to download the site's code or set up a local development environment. You just navigate to a webpage, open the Amino extension, and start editing. It's built for speed and simplicity, focusing on the core task of visual customization. While it's powerful for those who know CSS, its live feedback loop also helps beginners learn by seeing the direct impact of their code.

Web developers and designers will find Amino useful for quick prototyping and testing visual tweaks. It's also handy for power users who want to create permanent custom themes for sites they frequent, like applying a dark mode to a site that doesn't offer one. If you've ever wanted to change how a website looks without waiting for the site owner to update it, Amino gives you the controls to do it yourself.
