This is an experimental library for writing CSS in JavaScript. The current version is a beta and highly unstable, with changes happening on a daily basis. This library is not recommended for production use. It is actively being developed with your help.

Download
descartes.jsfrom thedistfolder -
Set up Descartes in a webpage by inserting it in your
<head>tag, like so:<!doctype html> <html> <head> <script type="text/javascript" src="/path/to/descartes.js"></script> </head> <body> <h1>I compute, therefore I am.</h1> <script type="text/javascript" src="/path/to/styles.js"></script> </body> </html>
-
Create a
styles.jswhere you will write your styles. Try the following:Descartes.add({ "body": { "color": "#555", "font-family": "Arial", "h1": { "font-family": "Helvetica", "font-size": function() { return 16 + Math.round(Math.random() * 42); } } } })
-
Save and open up your HTML file in a browser. Clicking anywhere on the window should randomize the size of your heading.
