Custom CSS by Denis

Minimal and secure way to add custom CSS per-domain
What is Custom CSS by Denis?
'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.
