evil.css

========

Mess with peoples' webpages. Various subtle and not-so-subtle CSS rules that will slowly drive people insane.

Inspired by [Upside-Down-Ternet](http://www.ex-parrot.com/pete/upside-down-ternet.html) and kitcambridge's [evil.js](https://github.com/kitcambridge/evil.js/).

Fork it and add your own evil rules. Worthy pull requests will be accepted.

How to use it

-------------

Inject it into unsuspecting users' webpages. evil.js was intended to wreak havoc on sites hotlinking JavaScript library files, however hotlinking CSS is far less common. Some other evil ideas:

* Set it as the user stylesheet in a browser (example: discouraging "customers" at retail stores from using the computers to browse Facebook and check their email).

* Inject it into webpages or CSS files served to WiFi leachers on your open access point.

* Exploit this week's WordPress vulnerability and add it to your friend's blog.

* Hack an Internet backbone router and inject it into _everyone's_ webpages.

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"

Demo

----

This bookmarklet will inject the latest version of evil.css into any webpage, just copy and paste into the URL bar and hit enter:

    javascript:(function(d,l){l=d.createElement("link");l.rel="stylesheet";l.href="https://rawgithub.com/tlrobinson/evil.css/master/evil.css";d.body.appendChild(l)})(document);
