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.

Add custom CSS styles on websites.

The extension does not require permissions to access all data on all websites all the time. Once you start editing CSS on a page, you get a permission prompt specific to that domain. Later, if the CSS for a domain is not used, the permission will be dropped.

There is no UI clutter of any kind. The entire extension consists of a big editable area for CSS code for the current domain.
