Take control of how the web looks with this Jx Minimal CSS Override a lightning-fast, zero-bloat extension that lets you inject custom CSS into any website. Whether you want to hide an annoying sidebar, fix a hard-to-read font, create a custom dark mode, or test design changes on the fly, Minimal CSS Override gives you the power to do it instantly. Unlike heavy styling extensions or the complex setup required for Chrome DevTools' "Local Overrides," this tool is designed for pure simplicity and speed. Just click the icon, type your CSS, and hit save. ✨ Key Features: - Persistent Styling: Your custom CSS is saved directly to your browser for that specific domain. The next time you visit the site, your styles are injected automatically. - Modern Developer UI: Write your styles in a sleek, dark-themed mini-editor built right into the popup. - Instant Apply & Clear: See your changes immediately without refreshing the page. Made a mistake? Hit the "Clear" button to instantly wipe the slate clean. - Ultra-Lightweight: No heavy background scripts or network interception. The extension simply checks your local storage when a page loads and injects a standard <style> tag, ensuring zero impact on your browser's performance. - Privacy First: All your custom CSS rules are saved locally on your own machine. The extension does not track you, collect analytics, or send your data anywhere. Perfect for: - Developers & Designers: Quickly prototype CSS changes on a live production site without digging through DevTools. - Power Users: Hide distracting UI elements (like sticky headers or chat widgets) on your favorite websites. - Accessibility: Increase contrast, change font sizes, or force readable colors on poorly designed sites.
