A script called
evil-safari-mac.sh is included that automates setting Safari's user stylesheet to the latest version of evil.css. Run it on any Mac using Terminal.app with this easy to remember URL:
curl -L bit.ly/evil-safari-mac | sh
Uninstall it by deselecting the stylesheet in Safari's preferences, or execute this in a shell:
defaults write "com.apple.Safari" "WebKitUserStyleSheetEnabledPreferenceKey" "1"
This bookmarklet will inject the latest version of evil.css into any webpage, just copy and paste into the URL bar and hit enter:
evil.css is purely for entertainment purposes. I'm not responsible for anything you do with evil.css, nor do I suggest doing any of the above activities, especially hacking backbone routers.
