Some of my styles I use with an user style sheet app.
(prerequisite: Stylus installed in your browser)
- install Stylus
- click on user.css you want
- click the "Raw" button, Stylus interface should open automatically
- click the "Install style" button
Install Stylus in Chrome: https://chrome.google.com/webstore/detail/stylus/…
More info on Stylus and links to install in other browsers.
BTW, don't use Stylish, it's poisoned.
