Super CSS Inject is a powerful Chrome extension developed by Nelson Rodrigues. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This free extension allows users to inject external CSS stylesheets into web pages via URL.

One of the standout features of Super CSS Inject is its ability to keep multiple stylesheets ready to inject and change on the fly. This makes it incredibly convenient for developers and designers working on multiple projects, as they can easily toggle between different stylesheets without any hassle.

Another great feature of Super CSS Inject is its compatibility with LiveReload. Users can work on CSS files without having to constantly reload the page, making the development process more efficient and seamless.

The recent updates to Super CSS Inject have further enhanced its functionality. The extension now addresses a bug that caused it to stop responding due to service worker inactivity. Additionally, it has improved its behavior in Single Page Applications (SPAs) by ensuring that the injected stylesheets always have the highest priority.

Overall, Super CSS Inject is a reliable and versatile extension for Chrome that streamlines the CSS injection process. With its user-friendly interface and convenient features, it is a valuable tool for web developers and designers.
