How do you add a horizontal scrollbar to an element? The overflow design
pattern in chapter 6 of my book, Pro CSS and HTML Design Patterns, shows exactly how to do this.
You can see an example of overflow in action at
http://www.cssdesignpatterns.com/Chapter%2006%20-%20BOX%20MODEL%20PROPERTIES/Overflow/example.html Ram Chml's code is a great example of how to do this. (Be sure, though, not to embed CSS directly within the style attribute of an element because this makes your code hard to maintain � instead use a class attribute and style the class in your stylesheet).
I don't yet recommend overflow-x or overflow-y because Opera 9 doesn't support these properties -- although all the other major browsers do.
Lastly, I don't generally recommend using overflow because it annoys users when they have to scroll to see something. Of course, I'm sure your case is one of the many exceptions to this generalization.
