Unobtrusive Seasonal Background

Separating your JavaScript completely from the HTML is relatively simple.

Adding JavaScript to your web page in an unobtrusive way means placing all the JavaScript in a separate file. This version of my seasonal background script shows you how to change the background image for part of the page based on which season it is without placing any JavaScript into the HTML at all (apart from the script tag of course).
