The tool I’m speaking of is SyntaxHighlighter. This must be one of the greatest tools I’ve seen in a long time, it’s easy to use, well designed and useful. As most people will know including code in your blog/webpage can be a challenge because of all the different characters that disturb original code or get interpreted wrongly by the content publishing system. This tool displays it all in a nice code view and allows the user to click “View source” to get clean code without line breaks.Example below.

body{
background-color: #FFF;
}
a{
color: #999;
}

I love it. You must get it, go to Alex Gorbatchev’s site and download.
