Daubpail: Custom CSS Editor

Daubpail is a custom CSS editor for changing how websites look in your browser.

Write or paste CSS for any site and watch the page change as you type. Pick an element on the page to get its selector. Your draft is kept locally until you save it or throw it away.

Build your own website themes and user styles, one for each job. Turn any style on or off, or pause them all at once. Each one runs only where you say: a single site, a site with its subdomains, addresses that start the same way, or a pattern.

Your styles stay yours as plain files. Export a full JSON backup or one CSS file, then import backups, section-based JSON or .user.css files. You see the list first and decide what happens to duplicates; anything unsupported is listed for review. This CSS injector has no style gallery and downloads nothing: it runs only the code you wrote or imported, and it blocks external resources.

• Make small website text easier to read.
• Give articles more room with your own CSS.
• Hide distracting page elements with a style.
• See edits live before committing them.
• Turn each saved style on or off separately.
• Pause all styles with one switch.
• Apply styles to sites, subdomains or address patterns.
• Recover locally saved drafts when you return.
• Review imported styles before changing your library.
• Export a JSON backup or an individual CSS file.

Works offline. Your data stays in your browser.

Permissions: local storage keeps styles and settings; scripting applies CSS and enables the element picker; active-page access identifies the page you choose; navigation events keep styles matched as addresses change. Site access is optional and requested when you allow it. Broad rules and cross-site frames need broader access. Protected browser pages cannot be styled.
