Custom CSS by Denis

Minimal and secure way to add custom CSS per-domain

Custom CSS by Denis - Chrome Extension for Per-domain CSS styling

'Custom CSS by Denis' is a browser extension allowing users to add custom CSS styles on websites they visit. The extension is dedicated to maintaining security and requires domain-specific permissions. Unlike other similar extensions, it does not access all data on all websites. The permission is prompted and given only when a user edits CSS on a specific domain and if left unused, these permissions get dropped. The extension maintains an uncluttered and minimal UI with an editable area for CSS code for each specific domain.
