The Snipplr WordPress Plugin is great, since it allows you to place code snippets by typing in something as easy as [snippet=123], where the 123 is really your code’s Snipplr Id. You also get the option to display the code’s author, the code’s title, or even to toggle code highlighting.

If you’re a Standards Compliant maniac, like me, then you’d probably want to edit your snipplr.php file and search for the $source variable. Replace it with the following code:

$source = "</p><p>{$title}{$author}{$comment}</p><div class='code' style='border: 1px dotted; overflow: auto; white-space:nowrap;'>$source</div><p>";

/* You should also set, in your WordPress Stylesheet, a 'code' class:
.code {
        font: 1.1em 'Courier New', Courier, Fixed;
        text-align: left;
        }
