CuCSS is a lightweight browser extension for applying your own CSS to any site. It is meant for small UI tweaks that make pages feel more personal.
It stores your styles locally in browser storage (based on the Web Storage API).

It displays a popup with a quick on/off toggle for the current site. A dedicated dashboard page provides a full CSS editor (powered by CodeMirror). The styles are stored internally, but it allows export/import them.
