Creating a Page Break
The folks over at 37signals have a blog post today about print style sheets. Basically, just add everything you don't want to print into one statement and set it to
display:none. I do the same thing here on Snook.ca.
I have an extra little tip that's also very applicable to those who run blogs: force a page break before the comments.
I do this so that people have the option to print the article with or without the comments. If they print just the article then it can stand alone in a nice clean package.
