CSS Input Autofill Style Generator
Build CSS autofill styles.
What the CSS Autofill Styles does
Build CSS autofill styles. This tool outputs the common WebKit autofill selector pattern used by Chrome, Safari, and Edge, including the long inset box-shadow trick for background color Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: Browsers often protect autofill backgrounds. A large inset shadow paints over that protected color more reliably than a normal background declaration.
Private and in your browser
Everything runs locally in your browser. Your input is never uploaded, so the tool stays fast and works offline, and the copy and download buttons always use the current result shown in the output panel.
