Let's say that I have a web page that uses a CSS style sheet loaded externally. I have no control over it.

This style sheet sets the margin attribute on the li element to 5 pixels.

In a class definition, I declare myclass.li to have certain attributes, and if I don't specify a margin, I get the value of 5 pixels as defined in the external CSS file.

So while I could specifically set margin to 0 pixels, I'd like to be able to say, "for this class's styling of li, please start from scratch."

Can that be done?
